Hrounding error

[cooperq at gmail.com]

Hi,
I am new to python.  I was messing around in the interperator checking
out the floating point handling and I believe I may have found a
rounding bug:

>>> 234 - 23234.2345
-23000.234499999999


This is not correct by my calculations.

I am using python 2.5.2 in ubuntu 8.04.  I am wondering if this is a
known bug, or if I am just not understanding some feature of python.
Thanks for the help!
