Boost.Multiprecision
A C++ library providing integer, rational, floating-point, complex, and interval number types with extended range and precision beyond built-in types.
What is Boost.Multiprecision?
Boost.Multiprecision is a C++ library that provides extended-precision number types, including integers, rationals, floating-point, complex, and interval numbers. It solves the problem of limited range and precision in C++'s built-in types, enabling high-accuracy calculations for scientific, cryptographic, and financial applications.
C++ developers working on applications requiring high-precision arithmetic, such as scientific computing, cryptography, financial modeling, and numerical analysis.
Developers choose Boost.Multiprecision for its flexibility, performance with expression templates, interoperability with Boost.Math and external libraries like GMP, and support for both arbitrary and fixed precision in a header-only, Boost-licensed backend.
