Taking the floor of a float

Question

I have found two ways of taking floors in Python:

3.1415 // 1

and

import math
math.floor(3.1415)

The problem

Answer 1

Beware that taking the floor and casting to an int are not the same thing with negative numbers. If you really want the floor as an integer, you should cast to an int after calling math.floor().

>>> int(-0.5)
0
>>> math.floor(-0.5)
-1.0
>>> int(math.floor(-0.5))
-1
