In D4 connecting to an Access database, I store data about a transaction such as price and quantity sold. I then apply tax to the subtotal. I store the price and tax info in currency variables (and the price is in a tcurrencyfield). I'm getting math errors in both the tax and total (gross) calculations. It's obviously due to rounding (I know this 'cuz I checked the raw values in debug mode). Since I want the automatic formatting (with the $ sign) of tcurrencyfields, how can I get around this error?
