%description
Mpfrcx is a library for the arithmetic of univariate polynomials over
arbitrary precision real (Mpfr) or complex (Mpc) numbers, without control
on the rounding. For the time being, only the few functions needed to
implement the floating point approach to complex multiplication are implemented.
On the other hand, these comprise asymptotically fast multiplication routines
such as Toom-Cook and the FFT.

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

%description devel
Development headers and libraries for MPFRCX.

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 "cc -q64" or "gcc -maix64".
