In 2.2 you have to go:

from __future__ import division

if you want division to default to floating point "true
division" i.e.

   >>> 3/2    # 3 and 2 are both type int
   1.5

That'll be phased out over time, meaning this type of
division will be the default.

Without importing anything, you can use the new // operator
any time, which forces an integer result e.g.

   >>> 3.0//2.0
   1.0
