Attila: This is not the problem. The database is well defined. Read the previous entries, please.

I understand that if instead use MyField.AsBCD, I use MyField.AsCurrency, I don't loss precision, because is his internal representation. Do you think? I'm going to do some proves.

Where is this info?: TBCDField converts the data from a BCD value to a currency value when it fetches the data from the database table, and converts it from a currency value to a binary-coded decimal value when it posts the data.

TBcd is a complex data type. I think I can't make mathematical operations directly with two TBCD types. I'm thinking in Currency type. But this implies convert every TBCDField value to Currency and vice-versa to assign the value from database to my variables and returning the values to the database. It's complex. I think. Anyone knows a good solution? Thanks in advance.
