(I an > not sure of either.) Mmmmmm ... the python C code implementing the math module is probably not that polymorphic <wink>. Even a call to "sqrt" does not work as expected if the argument is a long double. "sqrtl" should be use instead. Cheers, SB -- http://mail.python.org/mailman/listinfo/python-list
