longDescription = ''
The GNU MPFR library is a C library for multiple-precision
floating-point computations with correct rounding. MPFR is
based on the GMP multiple-precision library.
The main goal of MPFR is to provide a library for
multiple-precision floating-point computation which 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 (53-bit mantissa).
