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. http://docs.python.org/library/decimal.html 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. -- Senthil Q: What lies on the bottom of the ocean and twitches?
