Multiple-precision Floating-point library with correct rounding.

The MPFR library is a library for multiple-precision floating-point computation with exact rounding. The computation 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.


The MPFR Reference Manual is available here in various formats.
