ampclib is a simple to use platform independed C++ library for arithmetic multiple precision computations with a ritch and self explaining interface. It provides number theoretic functions and primality tests.
The ampclib consists of three classes:
+Integer (multiple precision integers)
+Rational (multiple precision rational numbers using the Integer class)
+Primes (prime number computations and number theoretic functions for unsigned 32 bit integers)
The latest release contains optimizations and bug fixes.
