Please read the Appendix on floating point issues in the Python Tutorial:

    http://docs.python.org/tut/node15.html

The actual fp product of those two numbers is strictly less than 1130.975.
You shouldn't have any such problem with FixedPoint if you're using it
correctly, but python-dev isn't the right place for this (so if you want
more on this, please use the newsgroup comp.lang.python).
