I've read the whole thread, and I wanted to repeat a critical point for
emphasis:
This doesn't help
No matter what you do to improve conversion issues, you're still dealing
with the underlying floating-point problems, and having watched the
changing discussions in c.l.py since we moved to the different conversion
system, it seems clear to me that we've improved the nature of the
discussion by forcing people to get bitten earlier.
Facundo's Decimal module is the only way to improve the current
situation.
