%description
The MPFR library is a C library for multiple-precision floating-point
computations with "correct rounding". The MPFR is efficient and 
also 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). MPFR is based on the GMP multiple-precision library.

%description devel
The static libraries, header files and documentation for using the MPFR 
multiple-precision floating-point library in applications.

If you want to develop applications which will use the MPFR library,
you'll need to install the mpfr-devel package.  You'll also need to
install the mpfr package.
