> casevh No... was not aware of gmpy2... looks like a great project! I am wondering why it would be sooo much faster? I was hoping that Stefan Krah's C accelerator was using FFT fast fourier transforms for multiplication at least... but, as Oscar pointed out a native python series algorithm runs right along with the built-in (at least for exp() and ln() ) I have not looked at Krah's code, so not sure what he did to speed things up... (something more than just writing it in C I would suppose). Thanks for the heads up on gmpy -- https://mail.python.org/mailman/listinfo/python-list
