This is design flaw in older versions of Python, that the / operator for ints performs integer division rather than floating point division. In Python 2.5 and beyond, you can fix this by calling from __future__ import division at the top of your module, and then / will perform float division with int arguments, and you can use // for integer division. Or upgrade to Python 3.1, where this is the default behaviour and there is no need for the from __future__ call. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
