A C library for multiple-precision floating-point computations
MPFR is a C library for arbitrary-precision binary floating-point computation with correct rounding, based on Multi-Precision Library. The computation is both efficient and has a well-defined semantics: the functions are completely specified on all the possible operands and the results do not depend on the platform. This is done by copying the ideas from the ANSI/IEEE-754 standard for fixed-precision floating-point arithmetic (correct rounding and exceptions, in particular)
