These files are for the TI-84 Plus CE, 83 Premium CE, and other "CE" calculators with color screens. BASIC programs are compatible with the TI-84 Plus CSE and some BASIC programs written for monochrome 83+/84+ calculators will also work correctly. Assembly and C programs must be written for the CE calculators specifically; running them on calculators with an OS newer than 5.5 requires jailbreaking the calculator.

  1. This program efficiently triangulates the position of a stronghold using two position and angle fixes obtained by sighting an Eye of Ender and recording the position and angle from the F3 debug menu. Not compatible with Bedrock Edition because it doesn't show your angle.

  2. A calculator program that simulates the calculator's math solving, but half the time it's random! Unless the answer is 2. There is a randomized wait time after you enter the equation. Replace the Version Number in the code with your calculator's Version Number. This version adds the dependences that are required to run the program.
    PLEASE NOTE: If you give the input text it spits out your previous answer but run through the randomizer again.

  3. It's a calendar.
    Should work on any calculator that has a clock.
    Displays the Month name, the Year number, a Calendar, with the current Day selected, and has a clock at the bottom.

    Update: Fixed a Domain Error that only happens in December

  4. This is a TI-BASIC utility to simulate stacks and queues using lists.
    Should work on the monochrome models, but I don't have a ROM or emulator to test this on.

  5. If you ever get in arguments, you should have this program! This uses Nash's theorem to settle any argument in the mathematically fairest way possible. In short, you come up with ways the argument could end and then you and who you are arguing with rate how they feel about each option on a scale from 0-10 (0 being worst imaginable, 5 being no preference, 10 being best thing ever), the calculator does many calculations with these and determines the best and fairest way the argument could end. More information about what this program does found here: https://drive.google.com/file/d/0B14cKdTCuh88dHlLQWtlUl9OalU/view?usp=sharing&resourcekey=0-CNS0gHLA8pWE-PVpvtN0Wg. P.S, the program still works if you don't want to do feelings on a scale from 0-10, and instead do something more precise with any amount like money gained/lost or people dead or something (just make sure you use a bigger number as being better).

  6. NORMCHK is a program for checking if your data follows a Normal (Gaussian) distribution!

    Note: This Normality check relies on finding the correlation coefficient of the Normal probability or quantile (a.k.a "Q-Q") plot of a variable. There are MANY ways to assess the Normality of a sample distribution; this is one of them.

  7. A highly optimized quiz program written in TI Basic for the TI-84 Plus CE. All the problems are randomly generated and after you have finished a quiz, you can see your accuracy and the number of problems you got correct.

  8. A simple program that allows you to calculate maximum heart rate, heart rate reserve, and target heart rate using the resting heart rate and percent ranges for the target heart rate (usually 60-85%). Only the TI-84 Plus CE is supported due to some of the margins I used for the text. (I haven't tested it on the base TI-84). (Please be gentle, this is my first program ever, and first time posting here. Thank you! ^_^)

    Program Name: HRCALCPE

    NOTE: When entering the lower and upper % limits, only enter the value; do not enter as a decimal and do not use any symbols. Read Me linked to this post goes more in depth.

    Please let me know of any other issues! :-)

  9. LineFinder
    This program finds the line that goes through all the given points.
    For now only up to 5 points or up to AX^4 + BX^3 + CX^2 + DX + E

    Including quality of life features like:
    Automatically make the formulas easier to read
    Graph the formula with all given points
    Displays the formula on the graph, and puts it into Y1.

    I put quite some work into this, I hope this is useful for someone.

    Bugfix added that would output impossible on possible equations

  10. This program allows you to input two values and perform either bitwise OR or bitwise AND on them. After selecting an operator via the [1] key or the [2] key, the program ends and outputs the result on the home screen.

    Since the TI OS doesn't have built-in support for bitwise operators, this program will allow you to calculate values with these operators if you need it to do so.

  11. get better at doing math in your head.
    you can test your addition subtraction multiplication and division skills.

    not the most beautiful UI but it works and keeps it a small program.
