Decimal arithmetic, with example code

Ok, here it is.  I have written some Python code which
displays the problems with float (floating binary)
arithmetic applied to monetary amounts.  Run this, and
many the places where the simple percentage times
amount calculation in floating binary falls down will
become obvious.

You need the fixedpoint.py module installed to run this.
