For example Euro is displayed with 2 decimals but internal calculations should be done with 4 decimals. If you are doing a lot of divisions/multiplications then you better don't limit the intermediate results or the rounding errors will kill the correctness of the result. I also recommend creating your own Money Class with a bigdecimal inside. Then you can add method to read/write the value with the correct number of decimal digits. -- Dirk Lukas Bradley wrote: > >> I always use BigDecimal for money, and convert to required formats >> when viewing.
