How To Round Off in Excel
Rounding off numbers in Excel can be done easily using built-in functions. To round, you simply need to use either the ROUND, ROUNDUP, or ROUNDDOWN functions, specifying the number you want to round and the number of decimal places. By the end of this guide, you’ll know which function to use and how to apply it effectively.
Step-by-Step Tutorial on How to Round Off in Excel
In this section, we’ll go through the steps to round off numbers in Excel. By following these steps, you will understand how to round to a specified number of decimal places, round up, or round down.
Step 1: Open your Excel spreadsheet
Open the Excel file where you want to round numbers.
Once you have your file open, locate the cell or range of cells containing the numbers you wish to round.
Step 2: Select the cell where you want the rounded number to appear
Click on the cell where you want the result of your rounding formula to be displayed.
This will be the cell where your rounded number shows up after applying the rounding function.
Step 3: Enter the ROUND function
Type =ROUND(number, num_digits) into the selected cell.
Replace "number" with the cell reference of the number you want to round, and "num_digits" with the number of decimal places.
Step 4: Use the ROUNDUP function if needed
If you want to round up, type =ROUNDUP(number, num_digits) instead.
Unlike the ROUND function, ROUNDUP always rounds numbers away from zero, making this handy for financial calculations.
Step 5: Use the ROUNDDOWN function if needed
For rounding down, type =ROUNDDOWN(number, num_digits).
This function always rounds numbers towards zero, which can be useful for estimates.
What You’ll See After Completing These Steps
After applying these functions, the cell will display the rounded number according to your specified decimal places. Any changes to the original number will automatically update the rounded result.
