You are right about rounding issues--with a sufficiently small step, the way I have done it, it could become an infinite loop. But you can still do it with multiplication, without using an epsilon constant. How about something like this: index = 0 while res < maximum: yield minimum + (step * index) index += 1 -- Michael Hoffman -- http://mail.python.org/mailman/listinfo/python-list
