%description
MPFR provides a library for multiple-precision floating-point computation
with correct rounding.  The computation 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).

%description devel
This package provides the header files and the symbolic links necessary
to allow compilation and linking of programs that use the libraries
provided in the %name package.

%description devel-static
This package provides static library necessary to allow static linking
of MPFR-based programs.
