%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.

The library is available as 32-bit and 64-bit.

%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.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "xlc -q64" or "gcc -maix64".
