high precision mathematics

[cmkl]

One of the dilettantic NASA amateurs (David Bailey) once wrote the ultimate 
fast and accurate MP-package 'mpfun' in Fortran 77 - later F90.
A C++ implementation is available at:
http://www.cs.unc.edu/Research/HARPOON/mpfun++/
I havn't tested this C++ version and I don't think there is a a python 
wrapper available (should not be to hard ??) but it may worth trying.
