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 mantissa). MPFR is based on the GMP multiple-precision library. The mingw32-mpfr package provides the documentation for the mpfr library, as well as the related development files. The associated mingw32-libmpfr package provides the runtime library.
