In my line of business (ledger/ERP/retail) I don't think I can normalize but chopping is definitely performed ?on each operation that can produce rounding errors. Luckily the number of decimal digits is fixed (almost always 3) and one can easily detect when there is a problem with rounding. However, there are cases like the one I described above (distribution) where deviations are inevitable, but it is usually acceptable to fix by slightly violating the rules, e.g. calculating the rounding error and adding it to a single row's amount in order to balance it out. But I feel I have hijacked the thread so I think I'd better stop.
