If you are using python2, an integer divided by an integer always returns an integer - >>> 10/3 3 It was changed in python3 to return a float - >>> 10/3 3.3333333333333335 You can reproduce the python3 behaviour in python2 by adding a 'future' directive - >>> from __future__ import division >>> 10/3 3.3333333333333335 HTH Frank Millman
