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

*Figure 1. The result of the ROUNDUP function*

**Syntax of the ROUNDUP Formula**

The generic formula for the ROUNDUP function is:

**=ROUNDUP(number, num_digits)**

The parameters of the ROUNDUP 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 ROUNDUP 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 number rounded up.

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

**Round a Number Up**

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

The formula in the cell D3 is:

**=ROUNDUP(B3, C3)**

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

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

- Select cell D3 and click on it
- Insert the formula:
`=ROUNDUP(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 ROUNDUP function*

When rounding the number, the function will always round a number up, regardless of the next decimal. We can see that in the cell D3, 2.34539 is rounded to 2.4. In the simple round, this number would be rounded to 2.3, because the next decimal is 4.

Most of the time, the problem you will need to solve will be more complex than a simple application of a formula or function.
