The NUMBERS calculator is designed to facilitate the computation
of number theoretic functions for positive integers of up to 150
decimal digits on almost any PC. The author's main objective in
writing NUMBERS was to allow students in a course in elementary
number theory to do nontrivial examples and pursue investigative
projects. Included operations are finding gcds, lcms, mod arithmetic,
quadratic residue test, Chinese remainder systems, number of divisors,
sum of divisors various pseudoprime tests, continued and Farey
fractions, Fibonacci numbers, Lucas numbers, encryption and decryption,
etc.
A collection of object files which can be linked into a Turbo
Pascal program are provided.
