   (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. ")
