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