Creal implements  *exact* real  arithmetic (i.e. all  computations are
exact and digits are computed later on demand). This is not to be used
when efficiency is really needed, but only when exactness is.

As Brian  already suggested, arbitrary  precision floats from  the GMP
library may  be useful in  your situation (but  as far as  I remember,
this part of GMP is not (yet) interfaced in mlgmp.)
