Actually no, floats don't meet this behaviour or more specifically floats don't guarantee this behaviour. It depends of course on your implementation of f, but it is possible with floats to keep incrementing and never reach a maximum. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
