python floating point calculations

Question

How should I expect Python to handle a simple floating point calculation like this:

float(6/4)

The output from this in the shell is

1.0

I would expect this to be 1.5, so what gives?

you are casting the RESULT of 6/4 into float, the result of int division is an int, instead do `float(6)/4` or `6.0/4` — Nullman, Feb 13 '17 at 17:09
`from __future__ import division` `a = float(5/4)` `print(a)` `output: 1.25` — Tony Tannous, Feb 13 '17 at 17:10

Python is using integer division here.

I see. Silly me, I should use 6.0/4.0 instead. Or, I could get cute and do something like (6 +0.0)/4. Thanks – Lazloman Feb 13 '17 at 17:09
@user675712 -- or, more future-proof, you should use `from __future__ import division` – mgilson Feb 13 '17 at 17:09
