If you are interested in doing fixed point arithmetic, the Python Standard Library has a decimal module that can do it.
Actually, it has a more flexible floating point ability than the built-in too. By flexible I mean that it:
Has "signals" for various exceptional conditions (these can be set to do a variety of things on signaling)
Has positive and negative
infinities, as well as NaN (not a
number)
Can differentiate between positive
and negative 0
Allows you to set different rounding
schemes.
Allows you to set your own min and
max values.
All in all, it is handy for a million household uses.
