TINT Package v1.2 Info

TINT, or TI Number Theory, is a package of lists and programs designed for number theoretic computation and analysis on the TI-83+ series of calculators. These programs are designed to be used as subprograms for larger projects, and are optimized for numbers less than 10^14. TINT's main feature is the precomputation of many arithmetic properties of a given input number stored for later use (e.g. number of divisors, totient function, etc.).

To install, simply download and open the group TINT, or you may download/copy individuals programs directly. All TINT programs are denoted by θNT followed by 2 or 3 characters. The following variables and lists are defined for an input N after executing the program θNTN. Most programs also require the factorization of N to be defined via θNTN (exceptions are noted below).

Updated in v1.1

• Removed all remainder( commands to allow support for older OS's
• Added primality/probable prime tests (see documentation for θNTPT)
• Added Lucas sequence generation (see documentation for θNTLS)
• Added more numerical properties to θNTIS
• Adjusted variable allocation for less shuffling (most inputs that are "bases" are now θ instead of Q)
• Better edge case support
• General bug fixes

Updated in v1.2

• Added Zeda's fast modular exponentiation algorithm (see documentation for θNTMZ)
