Program Archives: Utility
 Welcome to the TI-Basic Developer (TI|BD) Program Archives! We have a large variety of programs available for download, with program filtering and sorting based on genre and metadata, and will accept nearly any programs that you want to add to our archives. If you have questions, leave a post on the forums or read the FAQ. Happy gaming!

## CrisPI

Recite the digits of pi (π). How far can you go?

## fizz- buzz

this is a ti 83 version of the classic math game fizz buzz in which you count up from one and replace numbers with 3 or that are divisable by 3 with buzz and numbers that are divisible by 7 or have 7 with fizz

This program converts between the base 2, base 10 and base 16 numeral systems. [UPDATE: REDUCED IN SIZE (A LOT)]

## Oasis

Oasis is a basic shell for your calculator that will run basic programs.
You must have Celtic III (included) to run Oasis.

## Mnemon

This is a program to create data sheets and read them. You must input a random code of 6 letters/numbers which form your personal ID. It will make secure that nobody else can read your data sheets on their calculator!

## Evil

Randomly changes the results of calculations

## Battery Icon

Battery Level Indicator
Indicator program is in TI-BASIC
Battery Check program is in Assembly
Combined size of both programs (when the assembly program had been compressed) is 262 bytes.

## Quartic Equation Solver

Calculates the four roots of a quartic equation.

## Chars

Have you ever wanted to get some of those pretty nifty ASCII characters, such as the arrows, or subscript numbers? Well with this program, you can! I recommend just sending this to your archive and running it with a shell (such as MirageOS) so that it does not get deleted, as the program stores its awesome characters into Str7!

## Statistics Variable Solver

Calculates sample standard deviation, variance, population standard deviation, population variance, and the mean of a user-inputted list of numbers.

## Wave Interference Grapher

This program looks at two waves of the form ASin(BX+C) and graphs their interference pattern.

## Chemical Equation Solver

Balances chemical equations, inputted as a string.

## Solitaire Encryption

This is the Solitaire Encryption algorithm that Bruce Schneier made for Neal Stephenson's book Cryptonomicon. Before, only a TI89 version of the program existed. This is for the TI83/84s. Give your calc some time, and eventually something will come out encrypted/decrypted. The outputs are stored in Str1 and the decryption deck is stored in ∟DDECK.

## Right angle triangle solver Ultimate Edition

This is an easy to use right angle triangle solver that has error checking abilities and only requires an angle and a side or 2 sides.

This is the optimized version of my previous quadratic program. The functions are the same, but there are no errors and it is much more compact.

## Percent Error

This program solves for percent error.

## Digital + Anoluge Clock V1

A very compact (610 bytes) clock with accurate hands and a day indicator.

-Moon Phase Calc

This is a program where you input A,B, and C and it calculates the vertex of the parabola and then the roots (if any). As well as calculating these values, it also graphs the equation (stored into Y1). This is not shown in the program, but can be viewed after exiting. The program also includes a list of equation forms and a square root finder for calculating discriminants.

## GamePlayer Ultra

***This update is necessary if you are using an older version***
New to v0.6.1: re-worked setup; updated apps; many bug fixes; lots of optimization; slightly easier navigation

New to v0.5: setup bug fix; new ans updated apps; slightly faster; misc bug fixes

current version- v0.6.0

Full release of version 1.0 coming soon!!!

This program will simplify nearly any radical expression in the form of the nth root of x by removing the perfect n factors from under the radical.

This program features very fast load times, index reduction, and imaginary simplifications.

## Recurse

Two programs that recursively calculate the value of a function.

## TINT

A package of programs for number theory.

## Security Program

This is My first upload to this website!!!!! Yay!!!
