Python 3 integer division

Question

In Python 3 vs Python 2.6, I've noticed that I can divide two integers and get a float. How do you get the Python 2.6 behaviour back?

Is there a different method to get int/int = int?

[PEP 238](http://docs.python.org/release/2.2.3/whatsnew/node7.html) introduced the `//` floor division operator. — Jonathon Reinhart, Oct 22 '13 at 02:15

Try this:

a = 1
b = 2
int_div  = a // b

Note that `//` is available in Python2 as well (since 2.2, I believe). – Kyle Strand Jan 14 '16 at 17:57

Note that `1.0 // 2` and `1 // 2.0` maybe surprisingly return a float with value `0.0`. – asmaier Sep 12 '17 at 09:09

Floor divisions are NOT integer divisions. A floor division will return -2 for -3 / 2, while an integer division should return -1 (there's no floor or ceil in integer land). – Thorham Jun 14 '19 at 10:04
