About:
GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating-point numbers. It features highly optimized assembly code for many CPU architectures, making it exceptionally fast for complex mathematical computations. The library is widely used as a backend for languages and tools requiring high-precision math.

Key Features:

Arbitrary precision integers, rationals, and floats
Highly optimized assembly for multiple CPU architectures
C and C++ APIs with comprehensive documentation

Use Cases:

Cryptography and security applications requiring large integers
Scientific computing and high-precision simulations
Implementing language interpreters with big number support

Alternatives:

MPFR – Focuses specifically on floating-point arithmetic with correct rounding, often used alongside GMP for enhanced precision.
Boost.Multiprecision – C++ template library that can use GMP as a backend, providing a more modern C++ interface.
