How do I show decimal calculations in python?

Question

When I do a division in Python/Pandas (e.g. 47/100) how do I show the decimal value of the answer, because at the moment it just shows as 0?

Thanks in advance.

Python 2 uses integer division such that type(int/int)=int. This is a bug. Cast one of the operands to a float. — aestrivex, Jun 06 '13 at 15:19
@aestrivex: it is *not* a bug, the choice was deliberate. Python 3 made a different choice. — Martijn Pieters, Jun 06 '13 at 15:19
I consider it a bug. I consider there to be a lot of bugs in the language specification. — aestrivex, Jun 06 '13 at 16:05

If you're using python2.x, you need to "floatify"¹ one of your numbers:

float(47)/100
47.0/100

As python2.x will do integer division if both numbers in the division are integers.

Just another way: `operator.truediv(47, 100)` :) – Jon Clements Jun 06 '13 at 15:20
