It certainly would be slower than using native INTs and FLOATs but not devastatingly so. You can use INTs as Jerry suggests and pretend that decimals don't exist except for display purposes. So, for example, $1,524.79 would be stored as 1524790 which gives you three places of decimal precision (mils). -- Rich P.
