[docs] Doc Error

[Toby Hart Dyke]

On the first listing under 
http://docs.python.org/2/tutorial/introduction.html#numbers, it says:

>>># Integer division returns the floor:
...7/3

That may be true for python 2, but in my version of python 3 (3.3.1 on 
Windows 64-bit). It gives a float:

2.3333333333333335

There's a similar issue with the example before, where(50-5*6)/4 should 
give 5.0 rather than 5.

Thought you might like to know!
