In mathematics, integers are a strict subset of reals, but that doesn't mean that the integer type is a subclass of the float type. Floats in computers are not the same as reals in mathematics; most notably, they are far from infinite in either magnitude or precision. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
