GNU MP is a library for arbitrary precision arithmetic, signed integers
operations, rational numbers and floating point numbers. GNU MP is designed
for speed, for both small and very large operands. GNU MP is fast because it
uses fullwords as the basic arithmetic type, it uses fast algorithms, it
carefully optimizes assembly code for many CPUs' most common inner loops, and
it generally emphasizes speed over simplicity/elegance in its operations.
This package is needed to build programs written with GNU MP for use with
FreeBASIC.
