# TI-Nspire

The standard TI-Nspire calculator is comparable to the TI-84 Plus in features and functionality. It features a TI-84 mode by way of a replaceable snap-in keypad (included) and contains a TI-84 Plus emulator. The likely target of this is secondary schools that make use of the TI-84 Plus currently or have textbooks that cover the TI-83 (Plus) and TI-84 Plus lines, and to allow them to transition to the TI-Nspire line more easily.

# TI Nspire CX

The TI-Nspire CX is one of the latest updates to the TI-Nspire series. It has a thinner design with a thickness of 1.57 cm (almost half of the TI-89), a 1200 mAh rechargeable battery (wall adapter is included in the American retail package), a 320 by 240 pixel full color backlit display (3.2" diagonal), and OS 3.0 which includes features such as 3D graphing. With the exception of interchangeable TI-84 keypads, the CX series retain all features of the previous TI-Nspire models. The colors of the calculator are still the same as those of the TI-Nspire models; the CX is white and dark blue. In addition, the external connectors have changed slightly. The mini-USB port, located at the center of the top of the TI-Nspire series, has moved to the right on the CX series. Lastly, on the CX series, TI added a second port immediately left of the mini-USB port, for a new wireless module.

# TI Nspire CAS

The TI-Nspire CAS calculator is capable of displaying and evaluating values symbolically, not just as floating-point numbers. It includes algebraic functions such as a symbolic differential equation solver: deSolve(…), the complex eigenvectors of a matrix: eigVc(…), as well as calculus based functions, including limits, derivatives, and integrals. For this reason, the TI-Nspire CAS is more comparable to the TI-89 Titanium and Voyage 200 than to other calculators. Its likely targets are college students and universities. Unlike the TI-Nspire, it is not compatible with the snap-in TI-84 Plus keypad.

# TI Nspire CX CAS

The TI-Nspire CX CAS Is the latest update to the TI-Nspire series. It has similar features to the CX, It has a thinner design with a thickness of 1.57 cm (almost half of the TI-89), a 1200 mAh rechargeable battery (wall adapter is included in the American retail package), a 320 by 240 pixel full color backlit display (3.2" diagonal), and OS 3.0 which includes features such as 3D graphing. This calculator can be programmed in two types of programming languages: TI-BASIC and Lua.

Development articles for the Nspire are still very much underway. However, you can look at the beginners guide to gain some knowledge on Nspire Basic.

…that the Nspire can program in TI BASIC, C, Assembly, and Lua?

…that Nspires can program in BASIC, Lua, and C?

# What is IRC?

IRC stands for Internet Relay Chat, and is a tool that allows users to communicate with each other quickly and efficiently. An IRC comes in the form of a client, which means you would have to download it to be able to use it. There are many networks in IRC (common ones such as freenode, EFnet, IRCNet) and within those networks, you can find channels (where the "actual" communication takes place). The TIBD has its own channel named #tibasicdev, which is really useful for those who have questions regarding calculators or programming. Here is a tutorial that will give you step by step instructions on how to connect to our IRC channel.

# Step 1: Obtaining an IRC

The first step to connecting to IRC is actually getting an IRC client. There are many IRC's out there, but I will mention a few across the most common platforms. Here are my suggestions.

• Linux
• Windows
• Mac OS X
• iOS
• Android

# Step 2: Connecting to a network

For this tutorial, I will be using Quassel since it is easy to configure. Most other IRC's should setup similarly, so if you are using another IRC, the process should fairly be the same. Once you have an IRC client, open it up. A setup window should pop up. Click "Next" and you should see a "General" tab and "Away" tab.

Quassel Identity Setup

In the "General" tab, you can add nicknames that will show up as you in IRC, and you can also add your real name if you like. In the "Away" tab, you can add an away message, which is displayed when you leave the IRC.

Once you have configured those tabs, click "Next". You will then see a space asking for a Network. By default it will be on Freenode, but don't worry about this yet. Click "Save & Connect". From there, you will need to go to File>Networks>Configure Networks. You should see this screen.

Click on the "Add" button and another window should open. By default, you will be on the option of a preset network. Select "EFnet from the drop down list and press OK in the current window and Network window. You should be at the home page now (Make sure the network EFnet is highlighted before continuing).

# Step 3:Connect to a Channel

Now look near the top of the screen, and you should see four buttons (Connect to IRC Disconnect from IRC, Join Channel, Leave Currently selected channel). Click on "Connect to IRC" to connect to the EFnet network. You will know you are connected when the text "EFnet" is black (Gray text means there is no connection). Now click on "Join Channel" and you should see a window. Type "#tibasicdev" in the channel space, then click OK.

Join Channel

Congratulations, you are now at the TIBD channel! If you have any problems connecting you can discuss them here.

Thanks to jonbush and Pieman7373 for giving me the IRC's for Android and iOS :)

Are you new to Ti-BD? If so, then welcome to the community! This is a guide on how to do some of the basic things here on the forums. Let's start with the basics. Since you're reading this thread, I am going to guess you have already made an account. If you haven't, you can click here to Create Account.

# Rules

Be sure to read the rules and code of conduct! They can both be found here . Please read and adhere to both of them.

1. Click on the My Account button at the top of the page.
2. Navigate to the Settings tab
3. Click the button next to "Avatar" which says "Change"

1. Click on the My Account button at the top of the page.
2. Navigate to the Settings tab
3. On the left side of the screen, you will see a tab titled About me, click that
4. Add any information you wish to share

2. Navigate to the Settings tab
3. On the left side of the screen, you will see a tab titled Forum signature, click that

# Introducing yourself

2. Click on the "New Thread" button
3. Tell us about yourself! Common responses include Where are you from? What are some of your hobbies? What programming languages do you know?

# Making a Post

1. Navigate around forums! Find a thread you want to reply to. I personally like to use the Recent Posts page.
2. Make sure the thread isn't outdated. Threads more than two or three months old are likely inactive, and the user no longer cares about a response. We consider these dead threads, so please do not reply to them.
3. To contribute to the original post click on the "New post" button
4. To contribute to a specific reply or post, click on the "Reply" button under the post you want to respond to.
5. Edit the title if you want, although this is optional
• Note: you can use Wiki Markup in your reply to format it. Wiki Markup codes are found here
• Also note the "Char" Box in the upper right corner of the screen. It contains the TI-Basic characters that aren't readily accessed from the keyboard. It is meant to be a nice convenience for people who want to post code on the forum, allowing you to quickly copy and paste instead of having to hunt them down every time.

1. Navigate to the Discussion Forums. There should be a button for this on the sidebar.
2. Decide which forum most relates to what you want to discuss.
3. Near the top of the page, click on the "Create new thread" button
4. Add a relevant title, and a summary. Note that the summary should not be the same as your post, but rather a short description
5. Write your post. As with any other post, you can use Wiki Markups

# Adding a program to the archives

1. Navigate to the Program Archives. There should be a button for this on the sidebar.
2. In the box at the top of the page, there is a link to Add a Program to the Archive.
3. Enter a name for your program in the box, and then click "Create Program Page"
4. Fill in as much information as possible.
5. Add a download by clicking on the "Select File" Button. Most programs are in the form of .8xp .8xg .zip or .rar
6. If you do not have a download for your program, put the source code into SRC.txt and upload that, a site moderator may be able to compile the program later.
7. Hit "Save"
8. Your program is now on the archives!

1. On any thread, or in the screen for creating a thread, look for the "Forum Attachments" link near the top, or the "Files" button near the bottom
2. Clicking on this link will bring up a list of files
4. Browse your computer and select which files you want to upload
5. Click on the "Upload" button and wait for a confirmation message
• Note: you can attach these files using wiki markup. To show an image use [[image pagename/filename]]. To attach any file, use [[file pagename/filename]]
• To find the "pagename/filename" open the file list (see step 1). Right click on the title of the file you would like, and copy the link. Paste the link where "pagename/filename" goes. Remove the link except for the part after "local—files"

# Sending a message

• If you have a question for a specific user, you can send them a private message.
• Simply click on their avatar, and then the "Write Private Message" button.
• Alternatively, you can click on "My account" then "Messages" and look for the "New Message" button.
• Please note though, that we encourage public discussion, and that most content should be posted in threads.
• To see if you have new messages, look at the top of the page near your name. If you see (1) after your name, it means you have one new message. Similarly, (2) is 2 messages, (3) is 3, etc.

# Get involved

Getting involved is the best way to learn! Explore the site! There is a lot of information here on TI-BD, and it was contributed by users like you. Discuss, program, work with others. You can help this community grow by being active and involved here on TI-BD. Also, be helpful! Please try not to rely on the community to only help you. You should try and help others also. This means that you should also not rely on the community to create your code for you. Asking for a routine or optimization is okay, but we are not willing to write your whole program. This is a community that is here to help you learn, and the only way for you to learn is to do it yourself.

Command Summary

Enables a grid of colored lines on the graph screen.

Command Syntax

GridLine [color#]

Press:

1. 2nd FORMAT to access the graph format menu.
2. Use arrows and ENTER to select GridLine.

TI-84+ CSE/CE

2 bytes

The GridLine command enables a grid of colored lines on the graph screen (you can disable it with the GridOff command). How fine or coarse the grid is depends on the Xscl and Yscl variables. Drawing the grid just involves plotting points all the horizontal and vertical lines that intersect points of the form (A×Xscl, B×Yscl) that are in the graphing window. The grid can be colored based on any color variable or value.

GridLine can be used to shade the entire screen if Yscl is small enough that the lines on the grid are one pixel apart:

:ΔY→Yscl
:GridLine RED


This is one of the shortest ways to shade the screen, although Shade( can be used for a (usually) even shorter way. However, using GridLine is also very slow: the fastest way involves the Horizontal or the Vertical commands in a For( loop.

You could also use GridLine to draw the playing grid for a Dots and Boxes game.

Enables a grid of colored dots on the graph screen

Command Syntax

GridDot [color#]

Press:

1. 2nd FORMAT to access the graph format menu.
2. Use arrows and ENTER to select GridDot.

TI-84+ CSE/CE

2 bytes

The GridDot command enables a grid of dots on the graph screen (you can disable it with the GridOff command). How fine or coarse the grid is depends on the Xscl and Yscl variables. Drawing the grid just involves plotting points all the points of the form (A×Xscl, B×Yscl) that are in the graphing window. The grid can be any colored defined by a color variable or value.

:GridDot BLUE    //creates a grid of blue dots
:GridDot 12       //creates a grid of black dots

Command Summary

Returns the string representation of the value of the input.

Command Syntax

toString(value)

This command is found only in the Catalog. Press:

1. 2ND CATALOG to enter the catalog
2. T to go to commands starting with T
3. Scroll down to toString(.

TI-84+ CE OS 5.2

2 bytes

The toString( command, given any value including real numbers, complex numbers, lists, or matrices, returns the string representation of the value of the input.

toString(1337       //returns "1337"

toString({1,2,3}    //returns "{1,2,3}"

toString([[1,2][3,4]]   //returns "[[1,2][3,4]]"

toString(√-1     //returns imaginary number "i"


toString( has less limitations than the eval( command. It can handle lists, matrices, and complex numbers. Another difference from eval( is that toString( is affected by display mode changes like Fix.

toString( replaces the old number-to-string routine previously used prior to OS 5.2.

# Error Conditions

• ERR:DATA TYPE is thrown when the input is a string.
• ERR:NONREAL ANSWERS is thrown when the input is a complex number and your calculator is in REAL mode.
• ERR:SYNTAX is thrown when trying to evaluate a command that doesn't return a value.

Command Summary

Returns the string representation of the value of a real expression.

Command Syntax

eval(expression)

This command is found only in the Catalog. Press:

1. 2ND CATALOG to enter the catalog
2. E to go to commands starting with E
3. Scroll down to eval(.

TI-84+ CE OS 5.2

The eval( command, given an expression that evaluates to a real number, returns the string representation of that number.

eval(1337       //returns "1337"

eval(2.0-3.0    //returns "‾1"

eval(.0001234   //returns "1.234ᴇ‾4"


eval( has more limitations than the toString( command. It cannot handle lists, matrices, or complex numbers (even when the imaginary part of the complex number is zero). Another difference from toString( is that eval( is unaffected by display mode changes like Fix.

Use eval( in conjunction with expr( to evaluate a real expression in a string and return the answer in a string.

3.14->X
eval(expr("2X+3
//returns "9.28"


# Error Conditions

• ERR:DATA TYPE is thrown when the expression contains a list, matrix, imaginary number, or string.
• ERR:SYNTAX is thrown when trying to evaluate a command that doesn't return a value.

Example of Inputting Hex Code

There are all sorts of small assembly programs that you can create simply using the calculator's built-in assembly commands (specifically, AsmPrgm84C and AsmPrgmCE), along with the appropriate hexadecimal code. In order to run a program, you need to use the Asm( command, where Asm(prgmPROGNAME is the program that contains the hexadecimal code.

As a word of caution, when entering in the hexadecimal, you need to be very careful that you type it in exactly as you see it. If there is a single incorrect character, the calculator might crash and reset your RAM when you turn it on again. We have tested the hexadecimal codes to make sure they work, but it's up to you to enter them in correctly.

# Toggle Program Mode

:AsmPrgm84C
:FD7E08EE02FD7708C9


When used in a program, it allows you to use Archive and UnArchive on other programs. warning: Make sure to switch back to "program mode" when you're done by running the program again.

# Text Inverse

:AsmPrgm84C
:FD7E05EE08FD7705C9


This will switch from normal text mode to inverse (white text on black background) and vice versa.

# Lowercase

## Lowercase On

AsmPrgm84C
:FDCB24DEC9


## Lowercase Off

AsmPrgm84C
:FDCB249EC9


## Lowercase Toggle

AsmPrgm84C
:FD7E24EE08FD7724C9


This will toggle lowercase on or off

# Run Indicator [TO DO]

## Toggle Run Indicator

AsmPrgm84C
:FD7E12EE01FD7712C9


Note that when this routine turns the run indicator off, it doesn't erase the run indicator, it simply stops it. You can do this yourself — either by outputting something to the top right corner, or by clearing the screen (ClrDraw or ClrHome, doesn’t matter).

# Simulated Key Presses

## Alpha Lock

AsmPrgm84C
:3E51FD7712C9


This simulates [2nd][Alpha]

## Alpha Lock (No disable)

AsmPrgm84C
:3ED1FD7712C9


This is the same as the first, but you have to press [2nd][mode] to disable it.

## Lowercase Press

AsmPrgm84C
:3E31FD7712C9


This works even if lowercase isn't enabled.

## Lowercase Lock

AsmPrgm84C
:3E71FD7712C9


This simulates [2nd][Alpha][Alpha].

## Lowercase Lock (No disable)

AsmPrgm84C
:3EB1FD7712C9


This can only be disabled by pressing [2nd][mode]

## Alpha Off

AsmPrgm84C
:3E01FD7712C9


## [2nd]

AsmPrgm84C
:FDCB12DEC9


An interesting use of these codes can be for prompting user input (If you run Alpha Lock, for example, Input will start with an Alpha press.

If you run the Alpha Lock that can't be disabled at the start of your program and a user presses ON (or an error occurs), you will not be able to select the options, so you are forced to press [2nd][mode].

# Disabling "Done" Message

To disable the "Done" message at the end of a Basic program:

AsmPrgm84C
:FDCB00AEC9


# Un-Dirty Graph Screen

:AsmPrgm84C
:FDCB0386C9


This will mark the Graph Screen as not dirty. Using ClrDraw will mark the Graph Screen as dirty so the next time it is displayed the screen will be cleared. Many ASM libraries (such as xLIB) modify the graph buffer without displaying the screen which might be unintentionally cleared.

# Auto Calc

## Auto DMS

AsmPrgm84C
:FD360A06C9


Auto DMS displays all decimals in Degrees-Minutes-Seconds on the home screen, automatically.

## Auto Fractions

AsmPrgm84C
:FD360A0CC9


Auto Fractions will display decimals as fractions (if it can) on the home screen, automatically.

# Memory Functions [TO DO]

## Reset RAM

AsmPrgm84C
:C7


# Miscellaneous

## Remove Cursor

AsmPrgm84C
:FDCB0CE6C9


This is harmless, but it stops displaying that blinking cursor :D Just press [2nd][MODE] to put it back to normal. What, jokes are allowed, right?

## ASCII [TO DO]

AsmPrgm84CE
:EF7BCD500f02CD700F02CDB80702C9


Display an ASCII character at the last cursor position, using Ans (0 to 255) (TI-84 Plus CE)

This game is based roughly on games like Labyrinth of Touhou, however instead of 16 characters, you will be using two active characters who synergize well to fight bosses. It is currently a TI-Basic game which runs with xLib, and is in early development. Planned future updates include a boss tower, more characters, and hidden bosses.  Apr 14 — Members can now discuss TI-Basic on the #tibasicdev IRC channel on EFnet.  Apr 10 — After years of development by TI-BD members, the TI-Basic Starter Kit has been completed. Here are some review exercises to help you practice your optimization skills. 1. Write a program that, given a string in Ans containing letters A-Z, will return a list with the alphabetic positions of those letters. Example: "AZ AZ prgmLETTONUM Ans {1,26}  Possible Solution: 2. Change this short program so it doesn't flicker and then optimize it as much as possible. :0→X:0→Y:Repeat 0 :ClrHome :Output(Y,X,"X") :getKey→K :If K=24:X-1→X :If K=25:Y+1→Y :If K=26:X+1→X :If K=34:Y-1→Y :End  Possible Solution: In this chapter, you learned some optimization techniques to make your programs smaller and faster. • The Output( command can be used to display multiple lines of text by taking advantage of text wrapping. • The Text( command can automatically concatenate multiple arguments into one output • Storing large data used in multiple locations can save space. • Using implied multiplication and factoring out like terms in expressions can save space and time. • Understanding logical operators can help you eliminate extra parentheses to save space. Command Summary Returns the arc length of expression1 from start to end with respect to variable var. Command Syntax arcLen(expression1,var,start,end) Menu Location Describe how to get the command from a menu. This command works on all calculators. X byte(s) The arcLen() command uses the integral arc length formula to calculate the arc length of a function over the specified interval. arcLen(cos(x),x,0,π) 3.82019...  # Advanced Uses The arcLen() command also works on lists of expressions: arcLen({sin(x),cos(x)},x,0,π) {3.820... 3.810...}  Separate unrelated advanced uses with a horizontal bar. # Optimization This section includes both ways to optimize use of the command, and other common pieces of code that this command can replace in an optimization. Make sure to mention if the optimization improves speed of the program, size, or both. Sample code should be included too, preferably in the following format: :∫(√(1+d(f(x),x)²),x,a,b) can be :arcLen(f(x),x,a,b)  # Related Commands author: 'Kydapoot, optimized by Trenly and ZacharyPi' version: 1.1.1 summary: 'This is the optimized version of my previous quadratic program.

It is strongly recommended that you practice using these commands in different situations so that you will know which ones to apply when necessary. # Commands Introduced Command Summary Mode command that puts the calculator into Classic mode. Command Syntax MATHPRINT Menu Location Press: 1. MODE 2. DOWN until you reach Mathprint or Classic 3. ENTER on Mathprint Alternatively, use the catalog. TI-84 2.53MP or later 2 bytes MATHPRINT will put the calculator into Mathprint mode as opposed to Classic mode. In MathPrint mode, enhanced homescreen input formatting is available. The Classic mode will make the calculator display everything as a calculator of lower OS would, including input. For instance, rather than superscripting exponents as Mathprint mode would, Classic mode uses the simple caret syntax (^). Mathprint mode: 24 16 Classic mode: 2^4 16 When in Mathprint mode, text and numbers are displayed much slower than classic on the home screen and the function menus load slower. This can be inconvenient in games that use the home screen, but can also make solving equations that involve fractions and exponents easier as the numbers are in their correct positions and are the appropriate size. # Related Commands This page contains tables detailing which features were added with each operating system release.

W to go to commands starting with W. TI-84+ CE OS 5.2 or higher 2 bytes The Wait command was introduced in TI-OS 5.2 for the TI-84+CE. The Wait command tells the calculator to wait for a specified number of seconds before continuing. The specified amount of seconds can be a decimal, as it is not limited to whole numbers. This command can be useful for displaying information momentarily before proceeding in a program. The Wait command functions similarly to the Pause command, but without the extra arguments. :Disp "WAIT FOR IT! :Wait 4 :Disp "Surprise  # Advanced Uses The Wait command is useful for facilitating automatic linking within programs. Since the Get( and GetCalc( commands only work when the sending calculator is in a preemptible state, including a small Wait delay will allow the other calculator to receive data. Because the Wait command is relatively new, it may be advisable to avoid using it to ensure compatibility with older operating systems. Similar functionality can be achieved with the second optional argument to the Pause command. # Optimization Traditionally it was recommended to use either a For( loop or the rand( command to create a delay within a program. The For( loop takes more space, and the rand( command uses more memory during execution. :rand(100 can be :Wait 1  # Error Conditions • ERROR: INVALID is thrown if the Wait command is executed on the home screen. # Related Commands Please see the AsmPrgm page. The functionality and use is the same between both commands. However, the Asm84CEPrgm is only available on the TI-84+CE calculator.

Compatible with MirageOS.' description: "This program features a very basic Connect 4 game. The idea and interface were taken from a program made by CodeMaster123 that you can check out at http://tibasicdev.wikidot.com/forum/t-1441297/connect-4. I looked at his program and rewrote it from scratch to improve it whilst keeping his design, so feel free to download his too.\n\nFor those of you who don't know Connect 4, it's very easy. A typical Connect 4 game has two players: one who has a bunch of yellow (light) coins and one who has red (dark) coins. The board, which is an upright standing grid of slots, each slot the size to hold one coin, has walls between each of said grid's columns to seperate them from each other, meaning that when one drops a coin in a column, that coin will go all the way down to the first available slot in the same column. Every slot has a hole smaller than a coin on both sides, meaning that the two players can see what colour the coin inside that slot has. The players take turns on dropping their coins in the grid. The goal of the game is to get 4 coins of your colour in one line without being seperated by one of the other player's coins: this line can be horizontal, vertical or diagonal.\n\nThat said, these are the controls for this digital version of said game: You control the cursor (your \"hand\") with the left and right arrow keys and drop the coin in the designated column using Enter. Every time somebody drops a coin, the program will calculate whether or not 4 coins of the same colour were connected. This calculation takes approximately two seconds. After that, the playernumber in the bottom right will change, signifying that it's the other player's turn. Since this game is local multiplayer, you hand the calculator you're playing on to the opponent, so they can drop their coin. Then they pass it back to you, etc…\n\nPlayer 1's coins are light, player 2's coins are dark. The first to connect 4 of their coins, wins.

Player choose a house on their side of the grid, pick up the stones in that house and distribute them in the consecutive houses going in a counter-clockwise manner. There are many rule sets to mancala, just as there were many civilisations that played versions of it. This page gives two versions: The "kahla" rule set widely used in the United States and coded by user kg583, and another rule set coded by TI-GBR (rules are explained). ## Version 1: Kahla — Programmed by kg583 and optimised by the TI-Basic Developer community (see credits for details) — Compatible on both grayscale and color calculators ##### Version 1 rules: See wikipedia page describing "kahla" rules of play - "KAHLA" mancala ##### The Code, Version 1, Kahla Mancala ClrHome 14-->F F-->dim(L1 Fill(3,L1 0-->Xmin 1-->deltaX //The little triangle X {5,6-->L2 If Xmax=94 L2-{1,5-->L2 L2(1-->C L2(2-->D DelVar J1-->P Lbl M For(X,1,6 Output(C-1,D+2X+(X>3),L1(X Output(C+2,D+2X+(X>3),L1(F-X End L1(7-->H //Saves a couple of bytes to do this L1(F-->I Output(C,D+(I>=9),"_ _ _ Output(C+1,D+F,"_ _ _ Output(C,D+(I>=9),I //Greater than or equal to 9 Output(C+1,D+F,H If J Then Pause ClrHome If H>I Disp "Player 1 Wins!

Picture at start (Its been stretched a little) Each player, on their turn, chooses a house on their side of the board. (6 options) the stones from that house get distributed by picking them up, and placing 1 stone in each house consecutive to the last, going around in a counter-clockwise pattern until the stones run out. If the last stone falls in one of the wells, then the player gets another turn. The first player to clear their side of the board of stones wins. After first turn: player 1 has chosen the fourth house from the top, the last stone fell in a well, so player 1 will go again. Player 1 goes again. Now its player 2's turn.

If anyone experiences problems with the code on this page, please post on the "Discuss" page for this page. See the tools below. It seems that we are ready to make a mancala page. once it is made, feel free to edit it to relative perfection. Both games will be published, And credit given to those who worked on this community project. THANK YOU to all those who participated. we are starting a new ABSTRACT STRATEGY BOARD GAMES project featuring Isola. Please come participate in this continuation of this page, if you want to. ISOLA This is a continuation of Abstract strategy board games in which we programmed Mancala. the same rules apply to this community project- " In publication on the games page, credit will be given to the original contributor(s) of the code, and to those who helped optimise it. If there are many small optimisations, credits for the optimisations will be given to the Ti-Community, with a link to this page for clarification."

Here is the page describing Isola: Isola (isolation) Lets see what we can do to optimise this! Link to the original Posts: Here We have optimised the two games to a good point. They both work. the next step is to publish them on a new page titled "Mancala" under the games page. Symbolic Division is a method of finding the roots and factors of a polynomial given at least one factor. This is a function, rather than a program, and can be used in graphs, other functions, and programs. Rather than returning a list of factors as a result, we return an expression. # Code :synthdiv(colist,ftr) :Func :Local count,ansList,xexp,ansExp :expr("x")→xexp :0→ansExp :newList(dim(colist))→ansList :colist[1]→ansList[1] :For count,2,dim(ansList) :colist[count]+ansList[count-1]*ftr→ansList[count] :EndFor :For count,1,dim(ansList) :ansExp+ansList[count]*xexp^(dim(ansList)-count-1)→ansExp :EndFor :ansExp-ansList[dim(ansList)]/xexp+ansList[dim(ansList)]/(xexp-ftr)→ansExp :Return ansExp :EndFunc  # What's Going On? First, this is a function, not a program! To make a function, press F1 in the program editor, choose "3:New", and make sure the "Type:" is "Function" This takes 2 arguments, a list, and a number. We assume that's what we are given, and don't bother to check the type of the arguments. The first argument, colist, should be a list of all the coefficients in your expression. The second, ftr, is one single factor or root of your expression. ## Variables We then set up a few variables for our function. Functions can read global variables, but cannot write or create global variables! count is used in our For loops. ansList is a list of all the factors we want to return xexp is the expression "x". We use it to create the returned expression. ansExp is the factors in expression form. To prevent errors when making our expression, we set our answer expression ansExp to zero. We create the answer list using newList() with the number of elements in our given colist In symbolic division, you "drop" your first coefficient. We just store the first element of colist as the first element of our answer list ansList ## Dividing Now we start a For loop. We start from 2 since we already found our first answer above. The next line multiplies the previous answer by the factor, and adds that to the current coefficient, storing it in the next element of our answer list. ## Prettifying the Answer We start another For loop. Then we add our current expression to the answer list element times "x" to the power of the appropriate power. and store that as our answer expression. ## Fixing an Error After we prettify the answer, we have a mistake. Since the answer is an expression, we can easily subtract the mistake, and add our correction. ## Returning the Answer All Functions must return something using Return # Examples Here are a few examples of use. synthdiv({5,.46,84,.50,7},1/5) 5x3-45x2+75x-35 synthdiv({1,5,6},1) 12 -- +x+6 x-1 author: Michael2_3B version: '1.2' summary: 'Merge tiles together to rack up points!

Since there are so many rules to this game, we are developing two mancala games. Both need to be optimised for size and speed though! If you are good at optimisation, please come help us. Also, If you are interested in Helping us program a different board game please post about it, and we can move on to that one after mancala is finished. As far as I can tell, we only have a few participants in this project at the moment. This is your Basic connect 4 game. Drop Checkers down any of the 7 columns, taking turns until either the board is filled of one player gets four in a row. Try to understand the code. It uses Matrix [A] to track the game board, Var P as one or two to track whose turn it is, V as the input-ed column, L2 as the height of the columns, And Z as the counter for the possible number of turns. ## The Code DelVar [A]{6,7→dim([A] //sets [A] to 6x7 all 0's Disp" Disp"+-+-+-+-+-+-+-+ For(A,1,5 Disp"] End Output(8,1,"] For(A,3,8 Output(A,15,"[ End For(A,1,8 Output(A,16,sub("PLAYER_ _",A,1 //"_" is a space End DelVar θ2→P 7→dim(L₂ Fill(6,L₂ For(Z,1,42 If θ Goto 1 (P=1)2+(P=2)→P Output(8,16,P 2→V Repeat K=105 and L₂(.5V Output(1,V,"v Repeat K getKey→K End Output(1,V,"_ V+2(K=26 and V≤12)-2(K=24 and V≥4→V End .5V→V P(P=1)+(P-3)(P=2→[A](L₂(V),V) If P=1 Output(2+L₂(V),2V,"0 //zero If P=2 Output(2+L₂(V),2V,"O //letter O 0→θ If L₂(V)≤3 Then For(A,7,5,-1 cumSum(seq([A](A-I,V),I,1,4 If Ans(4)=4 1→θ If Ans(4)=-4 -1→θ End End For(A,0,3 cumSum(seq([A](L₂(V),A+I),I,1,4 If Ans(4)=4 1→θ If Ans(4)=-4 -1→θ End V+L₂(V->B If B≥5 and B≤10 Then seq([A](1,B-I),I,(B≤7)(B-1)+6(B≥8),(B≤7)+(B≥8)(B-7),-1→L₁ For(A,1,dim(L₁)-3 cumSum(seq(L₁(M),M,A,A+3 If Ans(4)=4 1→θ If Ans(4)=-4 -1→θ End End L2(V)-V→B If B≤2 and B≥-3 Then seq([A](I,I-B),I,(B≤-1)+(B+1)(B≥0),6(B≥0)+(B+7)(B≤-1→L₁ For(A,1,dim(L₁)-3 cumSum(seq(L1(M),M,A,A+3 If Ans(4)=4 1→θ If Ans(4)=-4 -1→θ End End L₂(V)-1→L₂(V End Lbl 1 ClrHome "PLAYER_ If θ=1 Ans+"1 If θ≠1 Ans+"2 Ans+" WINS!

Lets program some board games For anyone who is interested, there are several games that could be programmed. We would need to do them one at a time, posting code, optimising it, changing it, and then publishing it on the games page. here are some examples- 1. peg solitare 2. Go 3. Isola (Isolation) 4. Mancala … there are many possible others. If you're interested in participating in this community project, please post about your interest and which game you'd like to start on first, so we can get started. In publication on the games page, credit will be given to the original contributor(s) of the code, and to those who helped optimise it. If there are many small optimisations, credits for the optimisations will be given to the Ti-Community, with a link to this page for clarification. Routine Summary This is useful for factoring large nth degree polynomials (and finding their roots, of course), as well as finding an upper and lower limit for the roots of an nth degree polynomial, as per the remainder and factor theorems and some others. It uses L₁ for input of the coefficients of the starting polynomial, uses X for r in (x-r) (what you're dividing by), so have those variables predefined (or put :Input L₁:Input X at the the beginning of the program), and it outputs L₂ as the answer with the last list entry as the remainder. Inputs L₁ - the coefficients of the polynomial you want divide by (x-r) Outputs L₂ - the coefficients of the answer and the remainder is stored as the last list entry Variables Used L₁, L₂, A, R, Ans Calculator Compatibility TI-83/84/+/SE Author TI-GBR, optimized by earthnite dim(L₁→dim( L₂ L₁(1→L₂(1 For(A,2,dim(L₁ L₁(A)+R(L₂(A-1→L₂(A End L₂  Synthetic division works for problems in the following format. (a0xn + a1xn-1 + a2xn-2 + … + an-1x1 + anx0) / (x-r) Where a0≠0 For example, Problem: find the roots of x3-x2-2x-12=0 First we need to find all possible (r) in (x-r) Factor an:-12 {±1,±2,±3,±4,±6,±12 Factor a0:1 {±1 List of an/a0:{±1,±2,±3,±4,±6,±12 this last list is the list of all possible r in (x-r) Now for synthetic division. See the wikihow website Using the program. Input L1 with the polynomial's coefficients, {1,-1,-2,-12→L1 Input R for r in (x-r), 3→R We get a L2 as an answer, the last entry in the list is the remainder, if this is 0, we know that (x-r) is a factor.The other entries in the list represent the coefficients of the quotient, a polynomial of 1 degree less than the starting polynomial. so for starting polynomial f(x) divided by (x-r) , f(x)= (x-r) * q(x) +R, where q(x) is the quotient of 1 degree less than f(x) and R is the remainder. if R is =0 (x-r) is a factor of f(x) and f(x) can be broken down into q(x)*(x-r) Now, remember we found all possible r's? Well, do synthetic division for each of those r's until the remainder (R, the last entry on L2) is 0. when you have that, you rewrite your equation, so in our problem 3 for r gives 0 for R so we would rewrite the problem, using the coefficients as: Input: {1,-1,-2,-12→L1 Input: 3→R Output {1,2,4,0 This means that (x3-x2-2x-12) / (x-3) = x2+2x+4 (x-3) is a factor of (x3-x2-2x-12 Then use the quadratic formula with x2+2x+4 to find the other factors.

Features include: a toggleable move counter and timer, customizable difficulty, a built-in instructions booklet, MirageOS compatibility, a special hidden gamemode and more!' description: "NOTE: IT IS RECOMMENDED TO READ ALL OF THIS INFORMATION THROUGH BEFORE PLAYING THE GAME, AS IT WILL BE EASIER TO UNDERSTAND HOW EVERYTHING WORKS.\n\nHello there! My name is Mew, and may I firstly thank you for visiting my game's page! A lot of hard work has been put into the game, and I'm glad people appreciate that! Now, let me give you some info on it:\n\nTHE CONCEPT:\n\nBased on the ancient real-life puzzle, you start out with 3 pegs, the first one having a chosen amount of layers stacked decreasing in size on it. Your job is to move that stack, in the same order, from the first peg onto the last one, obviously following the rules.\n\n\nTHE RULES:\n\nThese are the rules you have to follow while solving the puzzle. Obviously it isn't possible to not do that anyway, since I programmed them in.\nI also included a shortened version of the rules (along with the controls) in the game itself, so that when somebody needs them but doesn't have access to this page, at least they have that.\n\n1. Thou shalt not move more than 1 layer at a time. This is pretty obvious, because otherwise you would be able to just move the whole stack at once.\n\n2. Thou shalt not move non-atop layers. Together with rule 1 this means that you can only move a layer if it is the upmost layer on its stack.\n\n3. Thou shalt not put big layers on small ones. This rule makes it so that at any given moment in time, there are no layers forming an upside down cone shape in the game.\n\n\nCONTROLS:\n\nWhile in the menus, you navigate using the arrow keys and the Enter key. While in the game itself, you use the left and right arrow keys to move your cursor, the up arrow key to lift a layer and the down arrow key to drop it. At any time in a game, you can restart by pressing 2nd, or Alpha to return to the main menu. \nAlso, so that you don't forget what peg you are taking from/adding to (due to e.g. distraction), there are arrows designating your choice of movement.\n\n\nFAQ\n\nQ: Why is there no leaderboard for highscores?\nA: There are 3 reasons for this: 1. I ran out of space on the menu screens, so I would have to redesign the whole menu system (which I'm not going to do) just to add a single extra option, 2. Because it would mean that for every number of layers I would need to have a leaderboard for time and amount of moves, meaning I would need 8 different leaderboards. I can't imagine how much extra navigating-code would have to be put into that… Finally reason 3: as I said already, I would need 8 different leaderboards, which obviously need to be stored somewhere outside of the program. I don't want to infest people's calculators with extra memory-consuming parts, which they may not know are taking memory. I don't want anyone thinking they have just the right amount of memory to use my program, but eventually get an out of memory message. I've had it happen before, it's not cool. So why are there time and move counters then? Well, you could use it just for personal measure, but if you really wanted to compete with friends (assuming you have them) you could always make a leaderboard yourselves.\n\nQ: Why is there a sentence on my homescreen when I quit, what does it mean and how do I get rid of it?\nA: The reason it is there is because it's my signature. Every program I write in TI-Basic I give a fitting phrase when it gets stopped. You can delete it like you delete your history, put your cursor on it and press delete. \nAs far as the meaning is concerned, it's a reference to the legend about the temple of Hanoi, where the priests guarding the temple have the same game (but in real life), which uttilises 64 golden rings. When the priests complete that puzzle (following the same rules as you have to in this game), it is said that that will be the end of the universe, or at least of humanity*.\n\nQ: Did you implement easter eggs?\nA: Maybe… It TOTALLY does not involve a secret code starting with K that rhymes with \"thee\" that has to be typed on the main menu using the arrow keys, 2nd, Alpha and Enter…\n\nQ: I can't use any of the options, is that a bug?\nA: Nope. To use an option, you first have to select it by pressing Enter, which will lock the cursor. Then, you can customize your options.\n\nQ: What do I do if I accidentally choose a wrong peg to take from/add to?\nA: Since there isn't an undo button for your last action, I would suggest selecting that same peg in the other direction: this makes the layer stay put, although it does add +1 to your move count.\n\nQ: Why does lifting a layer up and dropping it on the same peg count as a move?\nA: Because if you were to pick up a layer in real life and then put it on the same peg again, it would rather be seen as doing something as opposed to nothing.\n\nQ: I found a bug! What do I do?\nA: Post it below! I'd love it if others would like to help me improve my game by notifying me of bugs! After all, I'm only one person, and there might be flaws I didn't notice that others have.\n\nQ: What do I do if I have a question that's not listed in the FAQ?\nA: Like with the bugs, don't hesitate to post them below! I'll try to reply to everyone as well as I can.\n\n\n*This might not be such a crazy idea if you think about it. The minimum amount of moves required to solve the puzzle is 2^n-1, where n is the amount of layers in the puzzle. This means that for the puzzle the legend is talking about, that would be 2^64-1~1,844674407e19 moves! So, let's say hypothetically that from start to finish there's not a single interruption, every move is the right move to eventually finish with the minimal amount of moves possible, and let's say a move takes at least 2 seconds to complete. That means it would roughly take 1.169.884.835.000 years to complete! Technically, we can't really predict that far into the future, but the chances of that being \"the end\" are definitely not unexisting…" arcade: '1' graphics: '0' platform: '0' puzzle: '1' rpg: '0' strategy: '1' sports: '0' casino: '0' board: '0' utility: '0' misc: '0' compatibility: dd download: 'archivefile:hanoi-1/HANOI.8xp' image: 'archiveimage:hanoigif-1/Hanoigif.gif' fileSize: '4439' fileSizeUnit: '1' dateMade: '1439676000' Command Summary Changes the color of the graph border.

TI-84+ CSE/CE 2 bytes There are only 4 borders to choose from, so using the default colors will not work. Instead, you may only use a value between 1-4. For example, to change the border color to light blue, do: BorderColor 3  Here are the color values: Color Value Light Gray 1 Snowy Mint / Light Madang 2 Light Blue 3 White 4 The colors of borders 2 and 3 are not usable or accessible in any way except as a border color.

As you may know, you can also use the value of the color, which can be any integer between 10 and 24.

TI-84+ CSE/CE 2 bytes When DetectAsymOn is selected, the calculator will detect asymptotes, adjusting the graph accordingly. This method of graphing is the most accurate but is also much slower than graphing with asymptotes turned off. An asymptote is, by definition, "a line that continually approaches a given curve but does not meet it at any finite distance." Basically, an asymptote is the line where a function does not have any values on a certain axis. # Related Commands Command Summary Turns asymptote detection off.

TI-84+ CSE/CE 2 bytes When DetectAsymOff is selected, the calculator will not detect asymptotes, adjusting the graph accordingly. This method of graphing is much faster than with asymptotes turned on. However, the graph can be erroneous when dealing with rational functions, as it will often draw extra lines to connect points near undefined values. An asymptote is, by definition, "a line that continually approaches a given curve but does not meet it at any finite distance."

Highlight the area next to the word Answer to reveal the answer. If there are certain topics you don't feel confident in yet, don't worry. Just go back to the appropriate page and review. 1. True or False: Subtraction is the same as adding a negative number. Answer: True. 5 - 2 = 5 + -2 2. Which of the following expressions are equivalent? 1. abs(-5) 2. -30 / 6 3. int(-5.5) 4. 51 5. 30 / 5 Answer: Choices 1 and 4, which both equal 5. 3. True or False: The complex number i squared is equal to one. Answer: False. i2 = -1 4. Evaluate the following expression. Remember the Order of Operations. (1) $$24 / 4 + 2 * (9 - √9) / 3$$ Answer: The answer is 10. Remember PEMDAS 5. Which of the following commands will calculate the number of possible 3-digit number lock codes? The code can use the numbers 0 - 30 and order does matter. 1. 3 nPr 30 2. 30 nCr 3 3. 3 nCr 31 4. 31 nPr 3 Answer: Choice 4. Order matters, making the code a permutation. The length of the code, or r, is 3 digits, and the number of possible digits. or n, is 31, because we can use all numbers from 1 to 30 as well as 0. 6. True or False: The default base of log(n) is 10. Answer: True. To get a different base, use the logBASE function or the formula: log(x)/log(b) = logb(x) 7. Which of the following trigonometric identities is correct? 1. cos(x) - sin(x) = tan(x) 2. tan(x) + cos(x) = sin(x) 3. sin(x) / cos(x) = tan(x) 4. sin(x) * tan(x) = cos(x) Answer: Choice 3. 8.

They are harder to type and can make code look confusing, so it is better to write your program using normal variables, and then switch to the faster ones when you're done. Do NOT use C/Y if you are using P/Y, because if you set the value of P/Y, the calculator changes C/Y to the same number. Also do not use any of the X- or Y- window variables, because that will alter the graph screen. Use n, window variables, or finance variables when speed is important, because they take about 8000 fewer CPU cycles to access or store to, or about 0.5 ms on a TI-84 series calculator and 1.3 ms on a TI-83 or 83+.

//Finds first occurence of X in L1
1+sum(not(cumSum(L1=X)))

//Finds last occurence of X in L1
max((L1=X)cumSum(1 or L1))


Given a value in X, this code will search L1 and return the index number of the first (or last) occurrence of X.
For example, in a list L1={1,2,5,4}, the index value of the element 5 is 3. Storing 5 to X and running this code will return 3.

# Error Conditions

The first routine returns 1+dim(L₁) if L1 does not contain X, so if L1={1,2,5,4} and one searches for 9, the code will return 5.

The second routine returns 0 if L1 does not contain X, so L1={1,2,5,4} and one searches for 9, the code will return 0.

Command Summary

Press

1. 2ND DRAW to access the draw menu
3. Enter or 1 to select BackgroundOn

TI-84+CSE and TI-84+CE

2 bytes

With the introduction of color and a higher resolution screen than the monochrome calculators, the TI-84+CSE and TI-84+CE included the ability to display a background image on the graphscreen. The images variables are similar to the picture variables in that there 10 slots. In addition, functions can be drawn on top of images.

BackgroundOn recalls an image variable or color and displays it on the graphscreen.

:BackgroundOn Image1
is the same as
:BackgroundOn 1


Intrestingly, the following is a valid syntax, which fills the graphscreen with a light blue (18).

:15→B
:BackgroundOn B+3


In addition, BackgroundOn can be used to fill the graphscreen with a solid color. The color variables range from 10 to 24, blue to dark gray, as documented here. For example, BackgroundOn 12 will fill the graphscreen with black.

:BackgroundOn 12


# Error Conditions

• ERR:DOMAIN is thrown if the number is not an integer between 0 and 24.

# Related Commands

Please see the AsmPrgm page. The functionality and use is the same between both commands. However, the Asm84CPrgm is only available on the TI-84+CSE calculator. Keep in mind that hexadecimal for the monochrome calculators may not work on color calculators.

The TextColor( token is used to set the color for Text(. Although the default color is Blue, the calculator saves the color until it is changed again using TextColor( or when a memory reset occurs. When a memory reset occurs, the text color is reset back to blue.

:TextColor(BLUE

ORANGE 15
BROWN 16
NAVY 17
LTBLUE 18
YELLOW 19
WHITE 20
LTGRAY 21
MEDGRAY 22
GRAY 23
DARKGRAY 24

Each color token is 2 bytes.
The color tokens can be used in calculations. For example, LTBLUE/3 will equal 6.

# Background Colors

When the calculator displays text on the graphscreen, it displays it on top of a predetermined background color. This background color is white for all colors of text, except for yellow, white, and light gray (LTGRAY), which have a background color of medium gray (MEDGRAY). If you want to display text in your game without the annoying text-background, you need to have the graphscreen background be white or medium gray so the text-background doesn't show. The only known alternative is to use Pxl-On to draw the text manually, so how you work around this issue depends almost entirely on how lazy you are. You can see how this works by looking at the image in the Command Summary sidebar.

# Error Conditions

• ERR:DOMAIN is thrown if the argument specified is not an integer within the 10-24 range.

# Related Commands

…that the color tokens on a TI-84+CSE/CE can be used as number equivalents for math? For example, BLUE*5 equals 50 while DARKGRAY-4 equals 20?

description: "This is one of my most basic games, however it is still kind of addicting :P You must collect the falling \"+\" signs and avoid the falling \"-\" signs. Failure to do so will result in Game Over. Highscore included.\n\nCONTROLS: Left and Right Arrow keys to move, CLEAR to quit at any time."

summary: 'Recite the digits of pi (π). How far can you go?'
description: "Pi (π) is well known for its utility in all things circles (C=2πr, A=πr²). Pi is also known for being an irrational number, a number that goes on forever. This program won't help you memorize this number in its entirety, but it will help you remember the first 126!\n\n= OBJECTIVE\nFill the screen with the first 126 digits of pi, one digit at a time! Mistakes will set you back a little, but you'll also learn the next few digits. Don't give up!\n\n= CONTROLS\nNumber Keys 0-9: Type a number\nEnter: Continue after getting a digit wrong; proceed once you've completed all 126 digits\nClear: Exit the game. Progress is never saved.\n\n= TROUBLESHOOTING / RESTRICTIONS\nThis program currently uses the remainder() command, which is available on only operating systems past 2.53 MP. I'll remove this restriction in a future update.\nIf the program still doesn't work, try unarchiving any real variables or clearing a little space on your calculator.\n\n= MISCELLANEOUS\nThanks for checking out this program and reading this through! As a small thank-you gift, store pi to the variable X (π→X) before running CrisPI. You'll get a handy reference for the first 126 digits of pi.\n\n= LAST WORDS\nThis is my first program, so please feel free to comment on the program itself or on this page about anything I might have missed, programming tips, etc. Thank you!\n — IndigoWare"
