And if you want a safer way to deal with floating point numbers and to
kind of behavior we understand while doing it with paper and pencil,
use the Decimal module.
It behaves well with normal ints, floats and is supported for all
standard operations which are applicable for ints and floats.
Decimal module was aimed towards the use-cases which deal with finance
and astronomy/ scientific computing where decimal number behavior
needs to be consistent and should not be system dependent.
