perhaps not "precision-critical") calculation going on?
I'm summing up the bytes in use on a hard disk drive and generating a
report that's emailed based on the percentage of the drive in use. I
know there are other ways to do this, but I like Python and I like to
write my own code. I always find comp.lang.python a very helpful place.
So, from the sounds of it, you really care about this
rounding operation in the displayed values, in which
case the "'%.2f' % value" approach ought to be fine.
