What is ROUND function in Excel?
ROUND function is one of the Math and Trig functions in Microsoft Excel that rounds a number to a specified number of digits. For example, if cell A1 contains 23.7825, and you want to round that value to two decimal places, you can use the following formula:
=ROUND(A1, 2)
The result of this function is 23.78.
Syntax of ROUND function
ROUND(number, num_digits)
The ROUND function syntax has the following arguments:
- number: The number that you want to round.
- num_digits: The number of digits to which you want to round the number argument.
ROUND formula explanation
- If num_digits is greater than 0 (zero), then number is rounded to the specified number of decimal places.
- If num_digits is 0, the number is rounded to the nearest integer.
- If num_digits is less than 0, the number is rounded to the left of the decimal point.
- To always round up (away from zero), use the ROUNDUP function.
- To always round down (toward zero), use the ROUNDDOWN function.
- To round a number to a specific multiple (for example, to round to the nearest 0.5), use the MROUNDfunction.
