I was about to ask where!

anonymous · Answer

In Python 3.0 and above using the / operator for division will result in a floating point division rather than an integer division.

That's why you see a 3.0 result when using Python 3.1.

Hope that helps!

From a pure computer science perspective this actually deals with the limitations of doing division on binary computers. Each language must arbitrarily decide how to manage Integer division that would produce a remainder. It may truncate, it may round up. It doesn't matter it just needs to be known. If fractions matter then floating point numbers will be better but even they can't represent certain divisions properly. See: http://www.nr.com/
