The results make sense then. I had implicitly assumed that the special
functions were implemented from scratch and that you were relying only
on basic arithmetic. Seems like my practice of elementary functions
(where you are ultimately down to just polynomial evaluations and hence
only need additions and multiplications) played tricks on me there :).
