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