 The MPFR library is a C library for multiple-precision floating-point
 computations with exact rounding (also called correct rounding).  It
 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).
