Getting rid of some decimal places

My problem is: I need to have numbers formatted such that only two decimals are included with the number. (e.g. 102.34 instead of 102.3438869879) I need to import these numbers (it's a pretty good chunk of numbers, too many for manual deleting) into an Access database. When I import the numbers from Excel it includes all the decimal places regardless of how it appears in the Excel file. My problem is that I don't know how to get rid of the excess decimal places without going and manually deleting the numbers cell by cell. Also, I need the numbers to be formatted as numbers in access. In other words, I can't import as text. When I do, I change the formatting back to numbers and the decimals reappear. Please help, its driving me nuts.
