To round numbers to a specified number of decimal places using the ROUND function in Excel, follow these steps:
Open Excel and select a cell where you want the rounded result to appear.
Enter the number you want to round in a separate cell. For example, if the number is in cell A1, enter "=A1" in the selected cell.
Enter the ROUND function in the selected cell. The general syntax of the ROUND function is: "=ROUND(number, num_digits)"
The "number" argument is the cell reference or value that you want to round, and the "num_digits" argument is the number of decimal places you want to round to.
Replace "number" in the function with the cell reference where the number is located. For example, if the number is in cell A1, change "number" to "A1".
Replace "num_digits" with the desired number of decimal places you want to round to. For example, to round to 2 decimal places, change "num_digits" to "2".
Press Enter to complete the function. The result will be the rounded number with the specified number of decimal places.
Here is an example: If you want to round the number 12.3456 to 2 decimal places, follow these steps:
Select a cell (e.g., B1) where you want the rounded result to appear.
Enter the number 12.3456 in cell A1.
In cell B1, enter the following formula: "=ROUND(A1, 2)"
Press Enter. Cell B1 will display the rounded result as 12.35.
Note: The ROUND function follows the standard rounding rules, which means that if the next digit after the desired decimal place is 5 or greater, the number is rounded up. If it is less than 5, the number is rounded down.
