Hi! Tai is my family name and Shih Chau is my given name.

Well, if my applied is N(9,2), my discount is N(7,2), my allownce is N(7,2). SUM(applied+discount+allownce) gives N(16,2). However if I do SUM(applied+discount+allownce)*1000000.00/1000000.00, the result is N(30,4). I will never be able to get N(9,2).

Did I misinteprete your message?
