Floating point number on a binary computer are strange. They're not that
accurate. 0.07 * 100 != 7.0.

Try
>>> 0.07*100 == 7.0
0
>>> 0.07*100 - 7.0
8.881784197e-16

In Python 1.6, the interpreter doesn't try to hide this:
>>> 0.07*100
7.0000000000000009

For way too much info, look for old posts on this group by Tim Peters with
the words "floating point".
