The MPFR library is a C library for multiple-precision floating-point computations with correct rounding.
The MPFR library is built on the GNU Multi-Precision Arithmetic Library. It is licensed under the GNU LGPL v3 (or later versions).
The MPFR library is a C library for multiple-precision floating-point computations with correct rounding.
The main goal of MPFR is to provide a library for multiple-precision floating-point computation which is both efficient and has a well-defined semantics. It copies the good ideas from the ANSI/IEEE-754 standard for double-precision floating-point arithmetic (53-bit significand).
Both GMP and MPFR (and also MPC) are prerequisites when building the GNU Compiler Collection.
