Yes, Python does do an explicit check for a zero denominator. Here's an excerpt from floatdiv.c in Objects/floatobject.c: if (b == 0.0) { PyErr_SetString(PyExc_ZeroDivisionError, "float division"); return NULL; } This is probably the only sane way to deal with differences in platform behaviour when doing float divisions. -- http://mail.python.org/mailman/listinfo/python-list
