According to PEP 238:


"floor division will be implemented in all the Python numeric types, and will have the semantics of:

a // b == floor(a/b)

except that the result type will be the common type into which a and b are coerced before the operation."

But consider the following cases in Python 3.6.3:

>>> 0.9//0.1
8.0
>>> 0.8//0.1
8.0
>>> import math
>>> math.floor(0.9/0.1)
9
>>> math.floor(0.8/0.1)
8

Am I missing something?
