38 The GNU MPFR library is a C library for multiple-precision
39 floating-point computations with correct rounding. MPFR is
40 based on the GMP multiple-precision library.
41
42 The main goal of MPFR is to provide a library for
43 multiple-precision floating-point computation which is both
44 efficient and has a well-defined semantics. It copies the good
45 ideas from the ANSI/IEEE-754 standard for double-precision
46 floating-point arithmetic (53-bit mantissa).
