+Common-Description:
+ The MPFR library is a C library for multiple-precision floating-point
+ computations with correct rounding.  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
+ significand).
