gmp
The gmp package contains GNU MP, a library for arbitrary precision arithmetic which operates on signed integers, 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 full words as the basic arithmetic type, it uses fast algorithms, it carefully optimizes assembly code for many CPUs' most common inner loops, and generally emphasizes speed over simplicity/elegance in its operations.
Current version: 6.0.0
