Excel not calculating correctly

I'm working on a worksheet to determine the amount an employee is to be paid. In one cell I have the amount (N9=29.82) the other the amount of hours (O9=64). In P9 I have the total which is (O9*N9). The problem is that excel returns a total of 1908.76. The actual total is 1908.48.

This is a problem because the math error recurs in all cells with multiplication and I'm trying to link several worksheets for invoicing and will overpay by @ $30 each pay period if I dont go in and manually input the numbers. What can be causing this?

Note. the cells are formated to two digets decimls only.

The Rounding fixed everything, thanks!
