There is a line 177 characters long ;) Looks like a step in the right
direction, though. If you add the various operations of interest -- mul,
div, add, sub -- to the fixed_pt type you can make object arrays of them
pretty easily. Also, FixedPoint would be a more conformant way of naming the
class. The Decimal class in python 2.6 might be worth looking at, it is in
./Lib/decimal.py if you download the source. A description is at
http://docs.python.org/library/decimal.html .
