I agree with Micron. If you do not understand the rounding methods, your numbers could be off (could be issues). There are Banker's Rounding, Rounding Up, Rounding Down, Round To The Nearest, ....
Remember that Rounding (unless you are storing the rounded number in a table) only affects the display of the number.
So, in a query, you could try
Code:
Premium: IIf([Q2A]![E/NE]='N',([Q2A]![ByWkAccrual]/[Q2A]![SumOfCharged Hours])*0.5*[Q2A]![OT Hours],0) ' <<-- original
Premium: IIf([Q2A]![E/NE]='N',Round((([Q2A]![ByWkAccrual]/[Q2A]![SumOfCharged Hours])*0.5*[Q2A]![OT Hours]),2),0) ' <<-- with rounding
