Excel allows us to round a decimal number to a certain number of decimal places, by using the **ROUND** function. This step by step tutorial will assist all levels of Excel users in rounding a decimal number.

*Figure 1. The result of the ROUND function*

**Syntax of the ROUND Formula**

The generic formula for the ROUND function is:

**=ROUND(number, num_digits)**

The parameters of the ROUND function are:

**number**– a number which we want to round**num_digits**– a number of decimal places to round.

**Setting up Our Data for the ROUND Function**

In column B (“Number”), we have the list of numbers and in column C (“Number of decimal places”) we have a number of decimal places for rounding. In column C (“Rounded number”), we want to get a rounded number.

* Figure 2. Data that we will use in the ROUND example*

**Round a Number**

In our example, we want to round numbers from column B to decimals in column C.

The formula in the cell D3 is:

**=ROUND(B3, C3)**

The parameter **number **is the cell B3, while the **num_digits** is C3.

To apply the ROUND function, we need to follow these steps:

- Select cell D3 and click on it
- Insert the formula:
`=ROUND(B3, C3)`

- Press enter
- Drag the formula down to the other cells in the column by clicking and dragging the little “+” icon at the bottom-right of the cell.

*Figure 3. Using the ROUND function*

When rounding the number, if the next decimal place is greater than or equal to 5, the decimal is increasing by 1. We can see that in row 3, 2.76539 is rounded to 2.7654.
