# ROUND function: Description, Usage, Syntax, Examples and Explanation

## 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.
