number comparison problem

[Chris Fonnesbeck]

I am using python to code an optimization function that requires
numbers to be compared to one another, as is common in many
algorithms.  However, the comparison operators (<,>,<=,>=,==) seem not
to be working properly.  Regard the following:

>>> print fb,fc

0.132945911028 0.132945911028

>>> print fb>fc

1


These numbers look the same to me; what do I have to do to be able to
test numbers accurately in python?

TIA,
