%description
GMP is a free library for arbitrary precision arithmetic, operating on signed
integers, rational numbers, and floating-point numbers. There is no practical
limit to the precision except the ones implied by the available memory in the
machine GMP runs on. GMP has a rich set of functions, and the functions have
a regular interface.

The main target applications for GMP are cryptography applications and research,
Internet security applications, algebra systems, computational algebra
research, etc.

GMP is carefully designed to be as fast as possible, both for small operands and
for huge operands. The speed is achieved by using fullwords as the basic
arithmetic type, by using fast algorithms, with highly optimised assembly code
for the most common inner loops for a lot of CPUs, and by a general emphasis
on speed.
