This is a python library for arbitrary precision arithematic. This library is heavily used in a the python scripts which construct the tables of spin-weighted spherical harmonics and Legendre polynomials, for computing angular derivatives.
This is used for computing radial derivatives. I use FFTW to compute fast cosine transforms. There is a fortran module (src/mod_cheb.f90) which contains routines that directly compute the radial derivatives in Chebyshev space if you do not have FFTW.
The code will compile and run if you do not have OpenMP.
