Rounding functions in Excel

Rounding functions in Excel can be confusing. Luckily, Excel offers numerous built in functions to assist this process. Before we review the individual functions, it’s important to have an understanding on rounding in general.

Rules of Rounding

First, rounding in Excel follows the mathematical accepted rules of rounding. For example, numbers ending with 5, 6, 7, 8, or 9 round up while 1, 2, 3, 4 are rounded down.

Why Round at all?
