Often, you *need* to only display the result of your calculations with n
decimal places. Is yours such a situation? If so, forget the number of
decimal points during the computation and when printing format it as
appropriate ("%.2f").
If you genuinely want to work without the floating point problem that
you've indicated in your email, consider using the decimal module
>>> import decimal
>>> a = decimal.Decimal("79.73")
>>> b = decimal.Decimal("0.5")
>>> str(a + b)
'80.23'
[...]
Can you tell us *why* this inaccuracy is hurting you?
