28 The GNU MPFR library is a C library for multiple-precision
29 floating-point computations with correct rounding. MPFR is
30 based on the GMP multiple-precision library.
31
32 The main goal of MPFR is to provide a library for
33 multiple-precision floating-point computation which is both
34 efficient and has a well-defined semantics. It copies the good
35 ideas from the ANSI/IEEE-754 standard for double-precision
36 floating-point arithmetic (53-bit mantissa).
