summary    = A GNU arbitrary precision library.

description
	The gmp package contains GNU MP, 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.
