About:
MPFR is a portable C library for multiple-precision floating-point computations with correct rounding. It provides precise arithmetic operations based on well-defined semantics, ensuring results are as accurate as if computations were carried out in the target precision. The library is designed to be efficient and easy to use for scientific and numerical applications.

Key Features:

Correct rounding to any specified precision
Extensive set of mathematical functions
Portability across different platforms and compilers
Well-documented API with clear semantics

Use Cases:

High-precision scientific computing and research
Implementing accurate numerical algorithms
Financial modeling requiring exact decimal arithmetic

Alternatives:

GMP – GMP focuses on integer arithmetic, while MPFR specializes in floating-point operations with correct rounding.
