Command Summary

Computes the angle of a complex number or a set of complex numbers.

Command Syntax

angle(Expr1)expression
angle(List1)list
angle(Matrix1)matrix

The angle( command computes the angle of a complex number, which corresponds to the rotation of a vector whose length is equivalent to the abs( of the number. The angle is returned in degrees, gradians, or radians, depending on the mode the calculator is in.

Degree mode
:angle(1+i) = 45
:angle(1+i) = π/4


angle( can also return the angles for a list or matrix of complex numbers, returning the outputs in a list or matrix respectively. angle( will attempt to return a closed-form expression for the value rather than a decimal expression when utilizing the CAS, and can also return a symbolic evaluation of an angle.

:angle(z) = π(sign(z)-1)/2


# Formulas

The general formula for the angle of complex number x+iy is given by

(1)
\begin{align} \mathrm{angle}(x+iy) = \dfrac{\pi \times \mathrm{sign}(y)}{2} - \tan^{-1}\bigg(\dfrac{x}{y}\bigg) \end{align}

Often denoted as θ, the angle of a complex number is used in its polar representation

(2)
\begin{align} x+iy = re^{i\theta} \end{align}

where r is the absolute value of the number.

Command Summary

Boolean AND comparison of expressions or groupings of expressions.

Command Syntax

BooleanExpr1 and BooleanExpr2
BooleanList1 and BooleanList2
BooleanMatrix1 and BooleanMatrix2
Integer1 and Integer2

The and command compares two Boolean expressions (or lists or matrices of expressions) and performs the logical AND comparison, where the output is TRUE if and only if both inputs are also TRUE.

Command Output
0 and 0 0
1 and 0 0
0 and 1 0
1 and 1 1

and can also be used to simplify logical conditions. For example,

:x≥3 and x≥4
outputs
:x≥4


because, in order to satisfy both logical conditions, x need only satisfy x≥4. and can perform this process on a list or matrix of Boolean expressions:

:{x≥3,x≤0} and {x≥4,x≤-2}
outputs
:{x≥4,x≤-2}


which is the intersection of two inequalities. This can be thought of as the overlap of two regions of a number line, where x must lie in order to satisfy all of the logical conditions simultaneously.

and's final use is for bitwise comparison of integers. Consider two integers, 24 and 17, which when converted to binary become 0b11000 and 0b10001 respectively. To compare the two integers, and compares each bit of the binary number, outputing 1 when both bits are 1 and 0 otherwise:

0b11000: 24
0b10001: 17
-----  --
0b10000: 16


Integers can be entered in any base for use with and, including binary (0b) and hexadecimal (0h). The output will match the base of the inputs (if they are identical), defaulting to decimal.

This routine takes a single list, and randomly selects an element according to the bin sizes in the list. It copies the list so as to not overwrite the data. It then sums the list, and takes the inverse of the sum to use as an interval. It then generates a random number between 0 and 1. By testing if this number falls within the intervals defined by each partial probability, it determines which bin the random number falls into.

As an example, if the input is {4,11,2,3} there is a 4/20 chance that Bin 1 is chosen, an 11/20 chance for bin 2, 2/20 for bin 3, and 3/20 for bin 4. If a bin size is 0, it will be skipped and never selected as the probability is 0.

Routine Summary

Finds specific text in a string and replaces all occurrences with replacement text.

First, note that the input for the search string (Str2) and replacement string (Str3) can be modified for however you need them to be input. In this case, the texts "SEARCH" and "REPLACE" have been used as examples for these 2 strings.

To start off, we first store the length of the search string in variable J. Then, we check if the search string can be found in the main string. If not, the loop doesn't continue to run. Otherwise, we store the index in the string where the search string was found in variable I.

After this, we have to account for 3 distinct options:
1. The search string was found at the beginning of the main string
2. The search string was found at the end of the main string
3. The search string was found somewhere in the middle of the main string

So, we first put Str3 in Ans.
Then, if some of the string exists before the search string (so I>1), we add the replacement string in Ans onto that text.
After that, we check if the string exists after the search string (so I+J<1+length(Str1)), and if so, we add the rest of the text onto Ans.

After modifying the string like this, the program then checks if there are any more occurrences of the search string in the main string. If so, this whole process is repeated over.

Command Summary

Calculates the binomial cumulative probability, either at a single value or for all values

Command Syntax

for a single value:
binomcdf(trials, probability, [lower_bound,] upper_bound)

for a list of all values (0 to trials)
binomcdf(trials, probability)

From inside a document:
Press Menu, then scroll to probability.
Press the right arrow, then scroll to Distributions.
Press the right arrow, then scroll to Binomial Cdf (B)

This command is used to calculate the binomial cumulative probability function. In plainer language, it solves a specific type of often-encountered probability problem, that occurs under the following conditions:

1. A specific event has only two outcomes, which we will call "success" and "failure"
2. This event is going to repeat a specific number of times, or "trials"
3. Success or failure is determined randomly with the same probability of success each time the event occurs
4. We're interested in the probability that there are at most N successes

For example, consider a couple that intends to have 4 children. What is the probability that at most 2 are girls?

1. The event here is a child being born. It has two outcomes "boy" or "girl". In this case, since the question is about girls, it's easier to call "girl" a success.
2. The event is going to repeat 4 times, so we have 4 trials
3. The probability of a girl being born is 50% or 1/2 each time
4. We're interested in the probability that there are at most 2 successes (2 girls)

The syntax here is binomcdf(trials, probability, value). In this case:

binomcdf(4,.5,2)


This will give .6875 when you run it, so there's a .6875 probability out of 4 children, at most 2 will be girls.

If you wanted the probability that at least 1 and at most 2 will be girls, the syntax would be:

binomcdf(4,.5,1,2)


Another alternate syntax for binomcdf( leaves off the last argument, value. This tells the calculator to compute a list of the results for all values. For example:

:binomcdf(4,.5


This will come to {.0625 .3125 .6875 .9375 1} when you run it. These are all the probabilities we get when you replace "at most 2 girls" with "at most 0", "at most 1", etc. Here, .0625 is the probability of "at most 0" girls (or just 0 girls), .3125 is the probability of at most 1 girl (1 or 0 girls), etc.

Several other probability problems actually are the same as this one. For example, "less than N" girls, just means "at most N-1" girls. "At least N" girls means "at most (total-N)" boys (here we switch our definition of what a success is). "No more than", of course, means the same as "at most".

{compatibility} [[include inc:nspire-command-help |picture=@@ |summary=@@ |syntax=@@ |compatibility@@ ]] In general, omitting all the variables for a section is the way to go if you don't want the section to be displayed. The exception is "calculator compatibility" - omitting the variables for that section will display the default message (compatible with all calculators). ## |picture= If the image is embedded on the same page, then only the full name of the image is to be written here. Otherwise, simply paste the full URL of the image. ## |summary= Just type in a brief description of the command. ## |syntax= Enter the general syntax of the command. ## |compatibility If the command works on all calculators, simply say "All calculators." Otherwise, specify which calculator(s) the command is compatible with. Only one option can be applied (and they are exclusive of each other), otherwise unpredictable results may occur. Command Summary A short description of what the command does. Command Syntax The generic syntax of calling the command, with arguments. Menu Location Describe how to get the command from a menu. (Include this disclaimer if command xxxxx doesn't appear correctly due to markup limitations. See iff for an example) NOTE: Due to the limitations of the wiki markup language, the xxxxx command on this page does not appear as it would on the calculator. See Wiki Markup Limitations for more information. A complete description of the basic uses of the command. All commonly used and documented ways of calling the command should be listed here; inputs, outputs, and anything else important should be mentioned. :At least one piece of example code :should be included here.  # Advanced Uses Advanced uses include rarely used or undocumented ways of calling the command in question. If there's an unusual but effective way of using the command, that too should be listed. Another type of advanced use is a programming technique to which the command is critical. Finally, system variables modified by the program should be listed here. With each advanced use, you should have a piece of example code to show how it works, as well as an explanation. If there is already a page on the advanced use of the command, give a short synopsis, then link to that page - you shouldn't include the entirety of that page here. 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: :unoptimized code can be :optimized code  # Formulas (this section is usually not present) This section is unnecessary for most commands. The only ones that would require it are the ones on the high end of mathematical complexity, such as the statistics commands. Use the math template to type in a LaTeX formula that matches the rest of the page in background. For example, type [[include inc:nspire-math eqn = \sum_{i=1}^n\frac{a}{r^i}]] to get: (1) \begin{align} \sum_{i=1}^n\frac{a}{r^i} \end{align} # Error Conditions For the non-generic errors that might occur when using this command (that is, syntax-type errors shouldn't be included). In a format similar to the following: • ERR:DIM MISMATCH is thrown if the two list arguments have different dimensions. • ERR:RESERVED is thrown if ∟RESID is supplied as an argument. # Related Commands Several (around 3) commands have a similar function or are used in a similar context to this command. Make a bulleted list of them, with links to the other commands' pages. It will often be the case that several commands all link to each other. • Command 1 • Command 2 • Command 3 # See Also (this section is usually not present) If a command can be used in a particular design concept or technique, you should mention it and provide a link to its respective page. This section should come at the end of the page, and be a bulleted list that contains all of the design or technique related links mentioned throughout the page. • Design Concept 1 • Design Concept 2 • Technique 1  May 21 — Congratulations to TI-BD user Trenly for being promoted to Administrator! author: 'Bio_Hazard1282' version: '1' summary: 'Math Equation Puzzle Solver is a simple game you''ll just want to play when you''re bored.

It functions similarly to the Menu( command, in that it highlights the current menu option, and uses labels. To create your own menus, each menu needs a menu id, a string containing entries of the same length, the number of entries, the length of the entries, and the starting selection. What makes this code functional is that each menu option is referenced by a menu ID, and the number of the selection. Because of this, the same code can be used to display multiple menus. In addition to the up and down arrows and enter, a user can use the numberpad to select an option. The clear key will exit the program from any menu, and the delete key will return to the main menu from inside any menu. If the delete key is used on the main menu, the program will end. The main menu has an ID of 0 by default, and can be shown at any time using "Goto M0". Any sub-menus you wish to add should be in the following format. You will need to change O, L, and N for each menu. In the code below, O is set to 1. This is what gets referenced in the If statements in the main code. S is set to 1 since I want the first option to be selected when we load the menu. L is set to 22 in this example because each menu option is 22 characters long. You will notice there are spaces included to make sure each item is the same length. Finally, there are 6 options in this example, so N is set to 6.

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.

In this tutorial, we are going to show you how to BOOT TEST your calculator. (Or self-test) What this does it "tests" to see if everything is working correctly on your calculator. Here are some things you need to know… • Doing this resets all of your RAM • This test may take a while to complete successfully • There may be a chance of your calculator displaying a message: "ROM Fail" Lets begin the test. Press "Mode", then "Alpha" + "Ln" . Your calculator will display something like this: Don't worry, it will only clear your RAM. Press "Enter" twice. It will show this. If it shows "ID fail", don't worry, it means there is no PRODUCT ID. Press enter. It will then show the amount of RAM that your calculator can hold maximum. Press enter. There will be a counter that will increment by 1 about 6 seconds every time. Press "On" to skip this part. The screen test will now be executed. This will see if all pixels are working correctly. Press on to skip, or enter to go into the next phase. FIRST IMAGE TEST: ) After, it will test if all keys are working correctly. Press the keys that match the corresponding key code that is on the screen. After, the test is over and a RAM cleared screen will be showed. Here is a clip of the test being performed on a TI-84+ SE.

The easiest way to do this is to use a flag. What exactly is a flag? A flag is typically considered a placeholder or variable which contains a binary or Boolean value. In TI-Basic, it is typically a variable which holds a value of 0 or 1. This variable is called a flag because it is either up (1), or down (0). Flags can be very useful when used in the proper circumstance; They can help prevent double conditionals, allow for the program to behave differently based on which sections of code it has already run, or even change what a program does altogether. Let's look at an example: prgmFLAG :0→F :Lbl 1 :Disp "Flag is" :If F:Disp "Up" :If not(F:Disp "Down" :1→F :If not(F:Goto 1  In the code above, we see a very basic flag. The flag is either up, 1, or down, 0. The program will display that the flag is down, set it to be up, then say that it is up before exiting. That's a great start, but how can flags be used in more useful ways? ## Recycled Flags Recycled flags are flags that are used more than once for the same purpose inside of a program. They are commonly used within loops, but can be used in other ways depending on what you are attempting to do. Consider the following: You have a variable A which you want to compare to B; If A is greater than B, you want to display a message. The only catch is, if A is greater than 50 you want to display a different message. This is a perfect place for a Recycled flag, especially if you want to repeat the comparison with different values. Take a look at the following code: prgmACOMPB :randInt(1,50→B :Repeat A=B :1→T :Prompt A :If A>50 :Then :Disp "A is Greater than 50" :0→T :End :If T(A>B):Disp "A is Greater than B" :If A<B:Disp "A is Less than B" :End  Did you understand how it worked? If not, let me walk you through it. As you may have guessed, this is a very simple guess the number game. First, we store a value to B. This value doesn't particularly matter, but we want it to be 50 or less for this game. We create a repeat loop that will run until we enter the value of B. Next, we set our flag. I put this flag setting inside the repeat loop, since we want it to reset every time we enter a new number. The program will then ask the user for a value of A to test, and now this is where the flag comes in. The program tests if A is above 50, in which case it would be out of the range of values of B. If A is greater than 50, it displays that and sets our flag to 0, or turns it off. The next conditional tests if A is greater than B. If A is greater than 50, it will always be greater than B, but since we already determined if it was greater than 50, we don't want to accidentally display a message twice. If you take a close look at the statement, we are testing "If T(A>B)" which can be rewritten as "If T and A>B" or even "If T≠0 and A>B". Lets step back and look at the values of when we compared A to 50. If A was greater than 50, T got set to 0; If A was less than or equal to 50, T was left as 1. This means that the statement we are testing will only be true if A is less than or equal to 50 based on the value in T. ## Solitary Flags The flag in the last example was a recycled flag, meaning we used it multiple times. This is debatably the most common form of flags. The other type of flag is a solitary flag, or a flag that is only used once. Perhaps the best example of this is a program where the author wants the user to do something before running the program. A flag may be used to allow the program to give instruction to the user before executing the code. If A Then ClrAllLists Output(1,1,"Please enter data in L₁ Delvar A Pause Return End Disp mean(L₁ 1→A  While this is another simple piece of code, it displays a solitary flag very well. This program displays the mean of L₁, however we know that if there is no data in L₁ this code will throw an error. Lists are one of the variables that cannot be directly stored to using input or prompt, and because of this we want to tell the user to enter their data into the list. This code checks to see if there is a value stored in A, and if there is it then tells the user to enter the data, sets the flag, and exits. The reason this code checks to see if there is a value in A rather than if there is not a value in A is due to the fact that there will be a value in A most of the time. This program, for the flag, sets A to 0 by deleting it once it has told the user where to enter the data. When the program is run again, presumably after they have entered their data, it will see that there is no value and will then display the mean of L₁ as intended before finally putting a value back into A so it can be run again. author: 'Unknown User' version: 3.7.66.43.25TI83 summary: 'A FREE emulator of a TI-83 Plus, use this if you don''t own a TI-Basic Calculator!' description: 'A FREE emulator of a TI-83 Plus, use this if you don''t own a TI-Basic Calculator!' arcade: '0' graphics: '0' platform: '0' puzzle: '0' rpg: '0' strategy: '0' sports: '0' casino: '0' board: '0' utility: '1' misc: '1' compatibility: bb download: 'archivefile:vti83-20171201t150451z-001/VTI83-20171201T150451Z-001.zip' image: null fileSize: '777' fileSizeUnit: '2' dateMade: '' This is a simple program for yahtzee.

This will help both yourself and others in the future. One way to make your code more readable is to use indentation. Indentation is important because it allows you to easily see when one block of code ends and the next begins. Squashing all your code together with no indentation can make it hard to read. Indentation is usually done with one space per level. The calculator keeps track of how many spaces begin a line, so they will survive being tokenized. When you begin a block, such as If, or Loop, or While, you add a level of indentation to lines after it, and remove it when you reach an 'End', such as 'EndIf', 'EndLoop', or 'EndWhile'. Here's an example of good indentation: :indtexmp() :Prgm : © Prgm begins a block, so the rest of the code is indented : : Loop © Loop also begins a block, so add an indentation level : If getKey()=13 Then : Exit : EndIf : : Disp "Hello, World!" : EndLoop © EndLoop ends the block, so remove the indentation level :EndPrgm © EndPrgm is not indented at all  Indentation is going to be hard to maintain on a real calculator, or in many TI-Basic editors, since it isn't too common in the TI-Basic community. However, it will be worth it when you're working on a large program. Notice the blank lines before and after blocks like Loop. Like indentation itself, it is entirely optional and it only assists in reading the code. Here's an example of no indentation: :noindent() :Prgm :Loop :If getKey()=13 Then :Exit :EndIf :Disp "Hello, World!" :EndLoop :EndPrgm  This is a simplified example. Imagine an application with 10 or 15 nested If statements, each with their own Else and ElseIf statements. Now imagine needing to put code inside a specific If. You will most likely need indentation to keep track of where to put the code, or you might just sit there for a while trying to make sense of all those nested Ifs! It should be clear that indentation isn't required. Most members of the community don't use it for their programs, maybe because it increases program sizes, or because it's cumbersome to maintain. Maybe it just isn't worth the effort. You should decide whether indentation is for you. You could indent because it makes code more readable, or even just because you're used to indenting code. To indent, or not to indent? That is the question, and the reasoning for your answer is up to you. ## Commenting ## Variable Naming …that 68k calculators can not only program in TI-Basic, but can program in Assembly and C as well?

Enter the name of the variable that you wish to recall here, and press [ENTER]. For example, you could use Rcl to paste the contents of a string variable into an Input prompt in a running program.

This forum implements the TopicTree pattern for forum discussion. It uses a number of key Wikidot features:

• Live-templating, to format section and thread pages
• Cross-site includes, to pull in packages like the scrollbar
• Customizable themes

You can add special tags to thread pages to make them behave in certain ways:

• _sticky creates a sticky thread, which always shows first in lists of threads
• _closed pushes the thread to the end of the list and marks it "(Closed)"

Routine Summary

Reverses the order of elements in a list.

Inputs

L₁

Outputs

:dim(L₁→M
:For(L,1,int(M/2
:L₁(L→Z
:L₁(M-L+1→L₁(L
:Z→L₁(M-L+1
:End


This routine will quickly reverse L₁. It works by swapping pairs of elements that are equidistant from the center of the list, and uses no other lists as dummy variables.

Routine Summary

Calculates the mode(s) of a list of numbers.

Inputs

A,B - Whole numbers

Outputs

L₁(I) - Greatest common divisor (gcd) of A and B
L₂(I), L₃(I) - Bézout coefficients such that AL₂(I)+BL₃(I) = L₁(I)

Variables Used

I, Q

Calculator Compatibility

## Program Editor:

Before you start by making your first code, you must learn how to create a program(Make sure you are in the Calculator application). Press Menu and go to 8. Then, press 1 and 1 again. A window will pop up prompting the name of the program. Put in the name, then select the type (program or function) and press OK. Now, you are in the program editor, you can now move to the tutorials underneath.

## Introduction:

Well hello and welcome to your first tutorial! Let's start with the title "How to print text on a TI-Nspire", Well to simply answer your question it's Disp or text. Let's look at the two examples underneath.

Text "HELLO, WORLD!"

If you want to include more functionality to displaying text, you can use Disp which will display your text as well.

Disp "HELLO, WORLD!"
