Yes, that's http://en.wikipedia.org/wiki/IEEE_754-1985 http://en.wikipedia.org/wiki/IEEE_754-1985 specific. I like this explanation: http://docs.python.org/tutorial/floatingpoint.html#representation-error http://docs.python.org/tutorial/floatingpoint.html#represent... There is alternatives but don't forget that it is hardware issue not software. It looks like http://en.wikipedia.org/wiki/IEEE_754-2008 http://en.wikipedia.org/wiki/IEEE_754-2008 has decimal format thus it should address that.
