Hi ahmad, calculation with floating points in Python uses the IEE 754 (https://fr.wikipedia.org/wiki/IEEE_754) standard and will result in such quirks.

If you want to not loose precision you can use the decimal module:

>>> from decimal import Decimal
>>> Decimal('4.6')*100
Decimal('460.0')

Since this is not a bug if you have other questions when working with floats, try to ask on python-list or a forum.
