It would be fantastic to have a numerical evaluation of polylogs. (I
think the current version only gives single-float precision, all other
functions in maxima.)
If you have a reference to the algorithm, that would help a lot. That
might allow maxima to do a bigfloat implementation. If all there is is
the C code you mentioned, that would be helpful too.
