Problem with floating point precision

[j_mckitrick]

I checked the docs, but found nothing about floating point issues.

I am working on an app that deals with currency values, and only does
addition and subtraction (no division).  But I am starting to see
values that should be the same failing a compare!  What is the
workaround or correct way to compare 2 floats?  It worked fine for
months, then suddenly starting acting odd.  I might have upgraded
Python somewhere in between, I can't recall.
