How to round numbers in Excel using the ROUND, ROUNDUP, ROUNDDOWN Function

If you don't want to display decimal values ​​in Excel, you can simplify your numeric data with ROUND functions. Excel provides three functions: ROUND, ROUNDUP, and ROUNDDOWN. Let's see how they work.

Using ROUND functions in Excel is different from changing the format of a number. When you change the way a number is formatted, you only change the way it looks in the workbook. When you change numbers using ROUND functions, you change the way they look and are stored.

The ROUND function rounds a number to a specified number of decimal places. It rounds a number down if the digit to the next decimal place to the right is between 0 and 4, and it rounds up if the digit is five to nine. And as you might expect, the ROUNDUP function always rounds and the ROUNDDOWN function always rounds down.
