# How to Round up Numbers in Excel

## Use the ROUNDUP Function in Excel to Round Numbers Up

The ROUNDUP function in Excel is used to reduce a value by a specific number of decimal places or digits. This function will always round the digit upward, such as 4.649 to 4.65.

This rounding ability in Excel alters the value of the data in the cell, unlike formatting options that allow you to change the number of decimal places displayed without actually changing the value in the cell. Because of this, the results of the calculation are affected.

Negative numbers, even though they are decreased in value by the ROUNDUP function, are said to be rounded up. You can see some examples below.

### Excel's ROUNDUP Function

A function's syntax refers to the layout of the function and includes the function's name, brackets, and arguments.

This is the syntax for the ROUNDUP function:

`=ROUNDUP(Number,Num_digits)`

Number - (required) the value to be rounded

This argument can contain the actual data for rounding or it can be a cell reference to the location of the data in the worksheet.

Num_digits - (required) the number of digits that the Number argument will be rounded to.

• If the Num_digits argument is set to 0, the function rounds the value up to the nearest integer;
• If the Num_digits argument is set to 1, the function leaves only one digit to the right of the decimal point and rounds it up to the next number;
• If the Num_digits argument is negative, all decimal places are removed and the function rounds up that number of digits to the left of the decimal point upward.

Note: For an example of the last argument, if the value of the Num_digits argument is set to -2, the function will remove all digits to the right of the decimal point and round the first and second digits to the left of the decimal point up to the nearest 100 (as shown in row six in the example above).

### ROUNDUP Function Examples

The image above displays examples and gives explanations for a number of results returned by Excel's ROUNDUP function for data in column A of the worksheet.

The results, shown in column B, depend upon the value of the Num_digits argument.

The instructions below detail the steps taken to reduce the number in cell A2 in the image above to two decimal places using the ROUNDUP function. In the process, the function will increase the value of the rounding digit by one.

### Entering the ROUNDUP Function

Options for entering the function and its arguments include:

• Typing the complete function: =ROUNDUP(A2,2) into cell C3 in the worksheet;
• Selecting the function and arguments using the function's dialog box.

Using the dialog box simplifies entering the function's arguments. With this method it's not necessary to enter commas between each of the function's arguments like what must be done when the function is typed into a cell - in this case between A2 and 2.

1. Click on cell C3 to make it the active cell - this is where the results of the ROUNDUP function will be displayed.
2. Click on the Formulas tab of the ribbon menu.
3. Choose Math & Trig from the ribbon to open the function drop down list.
4. Select ROUNDUP from the list to open the function's dialog box.
5. Select the text box next to "Number."
6. Click on cell A2 in the worksheet to enter that cell reference into the dialog box as the location of the number to be rounded.
7. Select the text box next to "Num_digits."
8. Type 2 to reduce the number in A2 from five to two decimal places.
9. Click OK to close the dialog box and return to the worksheet.
10. The answer 242.25 should appear in cell C3.
11. When you click on cell C2, the complete function = ROUNDUP( A2 , 2 ) appears in the formula bar above the worksheet.
