That's not correct anymore. In Python 3 (and optionally in Python 2, if 
you do 'from __future__ import division'), the division operator (/) 
yields a float even for integers. The floor division operator (//) on 
the other hand yields an integer for integer operands, a float if one of 
the operands is a float.


 >>> 4/3
1.3333333333333333
 >>> 4.0/3.0
1.3333333333333333
 >>> 4//3
1
 >>> 4.0//3.0
1.0
