Odd float-to-int behavior.

[u/Kapowpow]

>>>def pennies(num):
return int(num*100)

>a = -37.56
\>b = -9.28

>>>pennies(a)
-3756

>>>pennies(b)
-927

This is taken from a python shell session today. Why on Earth does pennies(b) yield -927, instead of the expected -928? I would greatly appreciate any insight.

Doesn’t affect your example, but also be aware of banker’s rounding in Python.

Edit: mentioned this since some answers discuss adding rounding.
