Gives the exact value of an expression.
exact(expression)
Menu Location
 Press [2nd] [MATH] to enter the math menu.
 Press 1 to open the Number submenu, or use arrows
 Press [ENTER] to past exact(
Alternativly, for ti92/+/v200, type "exact(" using the keyboard.
This command works on all calculators.
6 bytes
The exact() command forces an expression to be evaluated in exact mode, temporarily ignoring the mode setting.
:exact(15.376)
1922/125
When applied to a complicated expression, matrix, or list, it forces every number that occurs there to be in exact form.
Related Commands
Calculates cumulative sums of a list or of the columns of a matrix.
cumSum(list or matrix)
Press:
 2nd [MATH] to access the math menu.
 3 to access the list submenu, or use arrows.
 7 to select cumSum(), or use arrows.
Alternatively, type cumSum( with the keyboard.
TI89/92/+/v200
7 bytes
cumSum( calculates the cumulative sums of a list, or of the columns of a matrix, and outputs them in a new list or matrix variable.
For a list, this means that the Nth element of the result is the sum of the first N elements of the list, and the N1th element of the result is the sum of the first N1 elements, and so on:
cumSum({1,3,5,7,9})
{1 4 9 16 25}
For a matrix, cumSum( is applied to each column in the same way as it would be for a list (but numbers in different columns are never added):
cumSum([[0,1,1][0,1,3][0,1,5][0,1,7]])
[[0 1 1]
[0 2 4]
[0 3 9]
[0 4 16]]
Advanced Uses
For a matrix, if you want to sum up the rows instead of the columns, use the ^{T} (transpose) command.
(cumSum([[0,1,1][0,1,3][0,1,5][0,1,7]]ᵀ))ᵀ
[[0 1 2]
[0 1 4]
[0 1 6]
[0 1 8]]

fPart(value) returns the fractional part of value. Also works on complex numbers/expressions, lists and matrices.
fPart(5.32)
.32
fPart([[‾1.5,3.2][6.8,‾7.9]])
[‾.5,.2]

fPart({‾1.5,3.2,6.8,‾7.9})
{‾.5,.2,.8,‾.9}
fPart(3.26+4.3i)
.26+.3i
Advanced Uses
To check if a number x is a whole number, you can simply check if the fPart(x)=0:
:If fPart(x)=0 Then
:©X is an integer
:Else
:©X is not an integer
:End

The E symbol is used for entering numbers in scientific notation.
mantissa E exponent
Menu Location
Press [2nd][EE] to paste the E command.
This command works on all calculators.
1 byte
The E symbol is used for entering numbers in scientific notation: it's short for *10^. Like TI83 Basic, the exponent of E must be a constant integer, however unlike TiBz80 the range of values is not finite.
The E symbol is used in display by the calculator for approximations of very small numbers, or when in Sci (scientific) or Eng (engineering) mode. Interestingly, the calculator will opt to display large numbers without approximation, but it will only solve for a maximum of 12 decimal places before rounding or using E.
Unlike the exponent of E, the mantissa (a special term for the A in A*10^B, in scientific notation) isn't limited to constants alone: it can be a real or complex variable or expression, a list, a matrix, or even omitted entirely (and then it will be assumed to equal 1). The reason for this versatility is simple: internally, only the exponent is taken to be an actual argument for this command. The rest of the calculation is done through implied multiplication.
5E3
………………5000
E‾5
……………….00001
Optimization
Don't add the mantissa when it's 1:
1E5
could be
E5
In addition, E2 or E3 can be used as shorthand ways of writing 100 and 1000 respectively. This could be continued, in theory, for higher powers of 10, but those aren't necessary as often.

Battle your way to victory by sinking the computer submarine!
The current game is 949 bytes in size, excluding the name.
The 1k version is pretty much complete. Try it out!
The source code:
Here are some of the bugs in the game:
 Gameplay is slow but fast enough to be playable
 Computer not smart enough
 Torpedos don't explode when they collide into each other
I have ideas on what the computer submarine should do:
 Dodge player torpedos quicker, either by going up or down
 Prevent both submarines going into each other, collision detection
 Prevent computer from going into mines
 Make the computer go to health blocks if they appear
Some ideas on updates for the game (Not for the 1k challenge):
 Plant mines around the map causing damage if any sub hits them (2x2 pixel blocks)
 Increase game speed
 Health blocks (Standard 1x1 pixels)
 Collision to prevent subs going into each other
 Quicker torpedo launches
 High scores
 Boss fights
 Increase submarine attack with XP and level system
 Timed fights
 Fire two torpedos at a time per player and computer

You just completed a project on your calculator you've been working on for quite a while. And you're wondering, "How can I back up my programs in case they get deleted?" This tutorial will teach you how to backup certain programs on your calculator or PC. Backing up is extremely important for keeping projects alive, and to not shoot yourself in the foot when you lose them all. Backing up on your calculator is one of the steps for backing up should you don't have a PC lying around. For starters,
let's talk about what specifically what types of files you can back up. You can back up anything; programs, lists, app vars, matrices, strings, all that stuff. But there's a price to pay when backing up. You must back up 2 or more files in your backup, else, it wont work. Another thing is you must have memory available. Backing up files must be in RAM, because the OS doesn't mess with files in archive. So without further ado, let's back up your projects!
Preparation
Ensure your files are in RAM, if they're in archive, unarchive them. Ensure you have archive space left, because backups are written to archive. On the calculator and across the Internet, backups are called groups. Groups are like "zip folders" containing files that were in RAM, and now in archive. These groups cannot be unarchived, so don't try to unarchive them.
Backing Up
To group your programs, press [2ND], [+], [⬆], then [ENTER]. Type in the name of the group of your back up. Press [ENTER] when you're finished. A menu will be shown indicating what files you can back up. If you are backing up many types of files (i.e., programs, pics, strings), it's best to select All. All+ selects ALL files in RAM, so you want to do the second option to select specific files. Use the arrow keys to move the cursor up and down to scroll through all the files, and hit [ENTER]
to select the file you want. A little black square will indicate that file will be backed up. When you have selected all the files you want, hit [➡] and select the option "Done". Your calculator should say or so "Copying variables to group: group name", then after it will show "Done" when the back up is complete. You're done!
Warnings
Yes, there are some warnings that you need to know. When you backedup your projects and there are some things you need to add/change, you do not need to constantly group your projects when you make small changes. Only do it once you make big changes. Doing so can slow the calculator down, and can sometimes do a backup fail. Backup fails is when the group fails to write to archive. Meaning, your calculator can simply shut off for no reason or just freeze at the "Grouping" screen. If it freezes, you are forced to remove a battery to escape this. RAM will be cleared the next time you turn your calculator on. Not although you lose your groups, you lose your projects as well. Why? Because they were in RAM when you attempted the backup, and when it crashed, they remained in RAM when you removed the battery. So now, your projects are permanently gone.
Keeping those projects alive
To keep your stuff from being deleted, make two groups when you back up for the first time. Then, when you make big changes, you delete the first group, then back up your projects. After a while, when you make even more changes, delete and back up to the second group. Keep doing this back and forth until you are 100% done with your projects.
But… what if those groups get deleted? Then you have nothing to spare! So what do you do now when you have the groups in archive and don't want them both gone? Back them up to your PC.
Backing up to your computer
Backups on your PC are harder to lose compared to your calculator. Files from your calculator are stored to your computer's hard drive, so they're not lost when your PC crashes. Cool, huh? So what do you do to back up files to your PC? It's not that simple as you may think it is. You need a special software for your computer to communicate with your calculator. Connecting your calculator won't just show up in Connected Devices. Depending on your calculator model, you may need either software:
If you have a TI84 Plus/SE/CSE/CE/T
Download TIConnect CE. This software is made for the 84+ family, and has a easytouse user interface. Requires Admin privileges to install.
If you have a TI83/+/SE, 89/Titanium, 85, 86, Voyage 200, etc.
Download TIConnect. This software is made for any calculator, including the 84+ family. This software can get slow and annoying, but it's old. Expect it to be slow. Requires Admin privileges to install.
Now you have the software. But aren't you forgetting something? Oh yeah! A linking cable. This is another important necessity for backing up to your PC. Most TI models don't have Bluetooth or Wifi on it (Except the newer NSpire calculators)! There are many different cables made specifically for your model/family. Links to purchase these will be added later, so stay tuned. Connect your calculator to your PC.
Backing up to your PC
Now make sure your calculator is on and has a good battery charge. Now find the software on your computer and open it. Find the option to send/upload files to your PC.
More detailed explanation will be explained later.
Wrapping Up
Now that you know how so send files to your PC and back up on your calculator, you can now not worry about losing anything!
Changes will be made onthego, expect more content on this page.
Uploading Help
Ever have any trouble with uploading content to the archives? Don't worry, this page will help solve that problem. Many people have trouble with uploading files to the archives, due to the dreaded AJAX error. So don't get upset if it doesn't work, there's nothing to get upset about. So follow these steps and tips and you'll be good to go.
I bet you want to upload your stuff ASAP, right? Don't you just cram as much info with the file and screenshot and hit submit? Well, hold on a second. That's not the way to go. You risk an AJAX error. For those of you who do not know what that is, let me put it this way. Once you get it, you can't really do anything after that error. You'll have to discard changes you've made to your archive page.
When you want to prevent the risk of that error, here are some things you can't put in your archive (yet):
 The download file
 The screenshot
Here are some additional rules you need to know about your archive. Doing any of these will probably throw an AJAX error:
 Keep the short summary less than 400 characters.
 Don't include any decimals in the file size. i.e., 4.2, 108.9, etc
 Don't spend too long editing the initial archive page.
If you kept the file and screenshot out of the way, good. Save your archive with only the information. No summaries or descriptions. Here are some tips you should do in case something happens:
 Keep your description and summary in a text document (Notepad for Windows or Text Editor for MacOS).
 Keep your files in the Downloads folder for easy access, so you don't have to scrounge your PC for the files and screenshots you need.
Make backups of your files unless they get deleted on accident. Deleted files on removable mediums will be deleted permanently, so be careful!
So now that you have your text document open and ready to copy and paste, and your files in the Downloads folder for easy access, you're ready to upload your archive! Edit your archive page, and copy and paste your summary and description. Add your file and screenshot. It is highly recommended that your uploaded file is a .zip archive. Make sure your screenshot isn't too big, or some of it will be cut off. The screenshots are intended to be captured by calculator screens. Now hit upload. If it said "Page Saved!", your good! Your archive was saved and your page is now viewable to other members of the site!

fPart(value) returns the fractional part of value. Also works on complex numbers, lists and matrices.
fPart(5.32)
.32
fPart(4/5)
.8
fPart(‾5.32)
‾.32
fPart(‾4/5)
‾.8
Advanced Uses
fPart(, along with int( or iPart(, can be used for integer compression.
Also, fPart( is an easy way to find A mod B (the positive remainder when A is divided by B).
:B(A<0)+iPart(BfPart(A/B))
If A is guaranteed to be positive, the following shorter code can be used, omitting B(A<0):
:iPart(BfPart(A/B))
Finally, the easiest way to check if a number is a whole number is not(fPart(X:
:If not(fPart(X:Then
: // X is an integer
:Else
: // X is not an integer
:End
You can use this, for example, to check if a number is divisible by another: if X is divisible by N, then X/N is a whole number. This is useful when you want to find the factors of a number. Warning: when storing values with repeating decimals and later multiplying them to see if a number makes it an integer it can return a value of 1 or 1 instead of 0 even if it is an integer. Example: if you store 1/3 as X and then do fpart(3x) it will return 1 instead of 0. This is because fpart(.999…) results in .999… and then rounds to 1 when displaying rather than rounding to 1.0 and then displaying the fpart( as 0.
Optimization
Often you want to find the value of a1 mod b — this occurs, for example, in movement routines with wraparound. However, the problem is that if a=0, a1 will be negative. Rather than use the longer version of the modulo routine, you might replace subtracting 1 with adding (b1). This will have the same result, but without sign problems.

A short description of what the command does.
The generic syntax of calling the command, with arguments.
The Ans variable holds the last answer that was stored in the calculator. Because Ans is stored in a special storage area builtin to the calculator, and it is extensively used by the calculator, you cannot delete it. Ans is also useful; it can make your programs both smaller and faster:
 Unlike other variables which have a value type hardcoded in (i.e., a string can only hold text, and lists and matrices can only hold numbers), Ans can take on whatever value you want: a real or complex, list, matrix, or string are all acceptable.
 Along with the finance variables, Ans is faster than the real, complex, list, matrix, and string variables; and subsequently, you should try to use it as much as possible.
One of the most common places to use Ans is in place of storing a value to a variable. Just paste the Ans variable to the location where the variable was called, and then when the expression is evaluated, the calculator will use the current value of Ans. Using the Ans variable allows you to eliminate the variable, which helps save a little or a lot of memory (depending on the type of variable and its size).
30+5A→B
Disp 25A,30+5A
;can be
30+5A
Disp 25A,Ans
The one major drawback to using Ans is that its current value is only temporary. Whenever you store a value to a variable or place an expression or string on a line by itself, Ans is updated to the new value. This restriction essentially limits your use of Ans to only a single variable. If you are manipulating two or more variables, it's best to just use the variables.
There are several cases in which changing the value of a variable does not modify Ans, thus preserving its current value for later use:
 storing to an equation variable
 using the DelVar command to delete a variable (i.e., set its value to zero, if it's a real variable)
 initializing or changing the value in a For( loop.
These cases can be very useful, allowing you to use Ans to store an expression rather than create a temporary variable for it.
A list is a collection of elements (made up of numbers, variables, or expressions). Although lists can have up to 999 elements (the only exception is the TI83, which can only have 99 elements), they are limited by the amount of free RAM. Besides the six builtin lists (from L_{1} to L_{6}), which can be accessed by pressing [2nd] and [1] to [6] (for whichever list you want), you can also create custom lists. A custom list name can be one to five characters, comprised of any combination of capital letters and numbers and theta, but it must begin with a letter or theta.
Lists are very versatile variables. They are used for storing highscores and map information, and just about anything else. Lists are also important because they are the only variable that can be assigned a name. This adds a certain security to using them. Other programs can still access your lists (and change or corrupt them), however, but there is a smaller likelihood of this happening simply because there are millions of possible names available.
To use lists, you must become familiar with some specifics of their syntax:
 The little ∟ command, which belongs at the beginning of any list name, except the default lists L_{1}…L_{6}. Almost always, when using a list, you must include this: e.g., to access the list SCORE, you would enter ∟SCORE. When you choose a list from the [2nd][LIST] menu, this is added by default so you don't have to worry about it.
 The curly brackets: { and }. These allow you to manually enter a list. When manually writing a list, you begin with putting a single opening curly brace ({) that will enclose the list. You then type a number or variable or expression, and put a comma after it. You repeat this for however many elements you want. You then put a single closing curly brace (}) that will close the list.
 Parentheses: ( and ). These access a specific element of a list: for example, ∟NAME(5) would be the 5^{th} element of ∟NAME. You can also use this to store to an individual element of the list.
Commands
List variables stand out from other advanced variable types because most commands you can use for numbers can be used for lists as well. In such a case, the command will be applied to each element of the list individually, and a list of the results will be returned. If two lists are used like this in the same command, their elements are "paired up" and the command will be applied to each pair. For example:
:cos({30,60,90
will be evaluated like
:{cos(30),cos(60),cos(90
:{3,4,5}={6,7,5
will return
:{0,0,1
Before doing any list comparison operations, you should first check that both list dimensions are the same size using the dim( command. This check is necessary because if the lists are not the same size, it will cause an ERR:DIM MISMATCH error. Of course, if you can guarantee their sizes will be identical, you can leave off the size check.
:If dim(L1)=dim(L2
:Then
:If min(L1=L2
:Disp "EQUAL
:End
There are some special commands for lists; some can be used for normal commands as well, but have a special meaning when used for a list. These are typically accessed through the [2nd][LIST] menu, and include:
Some statistical commands are used with lists as well: see the Statistics page for details.
Optimization
Some optimization tricks are used specifically with lists. For example, you may sometimes omit the little ∟ symbol at the beginning of a list. The most common situation where this applies is when using the → (store) command to store to a list. For example:
:{1,2,3→∟NUMS
can be
:{1,2,3→NUMS
This is even possible with a singleletter name, such as ∟X: the calculator will realize that you did not intend to store to the real variable X because lists cannot be stored to a real variable.
Another optimization that is possible is storing to the element just past the end of the list. For example, if ∟X has 5 elements, storing to ∟X(6) is also allowed. This increases the size of ∟X to 6 elements, and then sets its 6^{th} element as usual. The following is a standard construction to add an element to the end of a list:
:(value)→∟X(1+dim(∟X
You can even store to the first element of a list that doesn't exist. Because there are no elements in the list, the calculator will first create a new element at the beginning of the list, and then assign it the value. This optimization works especially well when looping with a For( loop, since you can use the loop variable as the list index.
Advanced Uses
Lists can be linked together in a way similar to an Excel spreadsheet using a quotation mark:
:"2L₁→L₂
After running this code, modifying a value in L1 will cause the corresponding element in L2 to be updated accordingly. Modifying a value in L2 will break the link. Connected lists are indicated by a ♦ symbol in the list editor on the TI84+, and by a small lock on the TI84+CE.
Returns the minimum of two elements or of a list.
 for two numbers: min(x,y)
 for a list: min(list)
 comparing a number to each element of a list: min(x,list) or min(list,x)
 pairwise comparing two lists: min(list1,list2)
min(x,y) returns the smallest of the two numbers x and y. min(list) returns the smallest element of list. min(list1,list2) returns the pairwise minima of the two lists. min(list1,x) (equivalently, min(x,list1)) returns a list whose elements are the smaller of x or the corresponding element of the original list.
min(2,3)
2
min({2,3,4})
2
min({1,3},{4,2})
{1 2}
min({1,3},2)
{1 2}
Unlike relational operators, such as < and >, min( can also compare complex numbers. To do this, both arguments must be complex — either complex numbers or complex lists: min(2,i) will throw a ERR:DATA TYPE error even though min(2+0i,i) won't. In the case of complex numbers, the number with the smallest absolute value will be returned. When the two numbers have the same absolute value, the second one will be returned: min(i,i) returns i and min(i,i) returns i.
Advanced Uses
min( can be used in Boolean comparisons to see if every value of a list is 1 (true) — useful because commands like If or While only deal with numbers, and not lists, but comparisons like L1=L2 return a list of values. In general, the behavior you want varies, and you will use the min( or max( functions accordingly.
Using min( will give you a strict test — only if every single value of a list is true will min( return true. For example, the following code will test if two lists are identical — they have the same exact elements — and print EQUAL in that case:
If dim(L1)=dim(L2
Then
If min(L1=L2
Disp "EQUAL
End
The first check, to see if the sizes are identical, is necessary because otherwise comparing the lists will return a ERR:DIM MISMATCH error.
Error Conditions
 ERR:DATA TYPE is thrown when comparing a real and a complex number. This can be avoided by adding 0i to the real number.
 Dimension Mismatch is thrown, when using min( with two lists, if they have different dimensions.

Hey! I just created an account to ask for some optimizations for my 3D rendering program for a TI84 Plus CE. I know matrices are slow to work with, so optimizations regarding that is the main goal for this. I've been coding in TIBASIC for quite some time, so I have sufficient knowledge of the language. This code was translated from The Coding Train (java) to BASIC, so the original code is not mine, all I did was port it over.
Feel free to drop by and contribute what you may, all help is accepted, including constructive criticism.
Here's my code:

Computes the angle of a complex number or a set of complex numbers.
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
Radian mode
: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 closedform 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)Often denoted as θ, the angle of a complex number is used in its polar representation
(2)where r is the absolute value of the number.

Boolean AND comparison of expressions or groupings of expressions.
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.

Finds specific text in a string and replaces all occurrences with replacement text.
Str1  The main string to modify
Str2  What to search for

Str1  the modified string

End
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.

This command is used to calculate the binomial cumulative probability function. In plainer language, it solves a specific type of oftenencountered probability problem, that occurs under the following conditions:
 A specific event has only two outcomes, which we will call "success" and "failure"
 This event is going to repeat a specific number of times, or "trials"
 Success or failure is determined randomly with the same probability of success each time the event occurs
 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?
 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.
 The event is going to repeat 4 times, so we have 4 trials
 The probability of a girl being born is 50% or 1/2 each time
 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 N1" girls. "At least N" girls means "at most (totalN)" boys (here we switch our definition of what a success is). "No more than", of course, means the same as "at most".

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:
If X<0
Then
⁻X→X

Another page that should be created similar to wikilimits
Unfortunately, the rich vocabulary of wiki syntax doesn't allow to properly display a command in titles and code blocks. When this happens, the offending page will link here so we can properly apologize, clarify what is meant, and give the syntax that displays them correctly where it is possible to do so.
Here are the commands and symbols that suffer from this problem:

This page should contain a list of all the errors from the tinspire. Would like it set up similarly to errors
This table lists all the possible error messages that can occur. The error number to the left is not displayed, but is stored to the errornum system variable, which can be used in a Try..EndTry block. Some error messages are very explicit (like #680), but others are less so. Where the error message itself gave too little information, this table explains the error more thoroughly.
A large part of the information here was taken from the Nspire CX Reference Guide at education.ti.com
Errors need to be added to the table below. Please alternate between using error1 and error2

This routine uses the List Frequency routine to find the frequency of each number. It then deletes, and reconstructs L₁ from the values in those lists by searching for the highest frequency, then adding it into L₁ the number of times it occurs. It then shifts the elements inside the frequency lists above the value down 1, overwriting the value which was just inserted into L₁. It then decreases the length of the frequency lists, and repeats until there are no more values to be added. This routine automatically cleans up, leaving L₂ and L₃ empty. If you wish to sort in ascending frequency, change the max( on line 12 to min(. If you wish to sort the values in ascending order instead of descending order, change the SortD( on line 1 to SortA(

Return
This menu is made for the graphscreen on monochrome calculators. 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 submenus 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. We then Goto M to display the menu

Example of Inputting Hex Code
There are all sorts of small assembly programs that you can create simply using the calculator's builtin assembly commands (specifically, Asm84CEPrgm 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.

Introduction
Celtic III is a Flash Application for the TI83 Plus, TI83 Plus Silver Edition, TI84 Plus, and the TI84 Plus Silver Edition graphing calculators, designed to extend the functionality of these calculators so that BASIC games and utilities can perform actions that cannot easily be done through the language itself. Celtic III supports its own command set focused more on file handling and manipulation. It also supports a command set used for manipulating image files and screen data. It also supports decent compatibility with the popular xLIB library so you don't have to change anything.^{1}

When programming, you may find that you want to execute a piece of code based on if another section of code has been executed. 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 TIBasic, 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"
:If F:Return
:1→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.

This is a program that is like the Pen command.
Let's make a program that could define the variable B, as (10^10). Let's start!
Count()
:Prgm
: Local a,b
: 10^10→b
: For a,1,b
: Disp a
: EndFor
:EndPrgm
Let's break this code down piece by piece starting from the beginning.
counting()
:Prgm
The first code is the title of the project called "Count()" but you could make it whatever you want. While the second code is ": Prgm", which let's the calculator understand that it is a "program".
: Local a,b
: 10^10→b
: For a,1,b
: Disp a
In this code, a "For loop" is established, which will store each successive number from 1 through B (10^10) in variable A.The program then outputs the data currently stored in Variable A, to character space 1,1 in the screen
: EndFor
:EndPrgm
For this segment, "EndFor" ends the for loop after the code is executed. While "EndPrgm" ends the code.
