## Summary

The Excel ROUND function returns a number rounded to a given number of digits. The ROUND function can round to the right or left of the decimal point.

## Purpose

Round a number to a given number of digits

## Return value

A rounded number.

## Syntax

``=ROUND(number,num_digits)``
• number - The number to round.
• num_digits - The place at which number should be rounded.

## How to use

The ROUND function rounds a number to a given number of places. ROUND rounds up when the last significant digit is 5 or greater, and rounds down when the last significant digit is less than 5.

ROUND takes two arguments, number and num_digits. Number is the number to be rounded, and num_digits is the place at which number should be rounded. When num_digits is greater than zero, the ROUND function rounds on the right side of the decimal point. When num_digits is less or equal to zero, the ROUND function rounds on the left side of the decimal point. Use zero (0) for num_digits to round to the nearest integer. This behavior is summarized in the table below:

Digits Behavior
>0 Round to nearest .1, .01, .001, etc.
<0 Round to nearest 10, 100, 1000, etc.
=0 Round to nearest 1

### Round to right

To round values to the right of the decimal point, use a positive number for digits:

``````=ROUND(A1,1) // Round to 1 decimal place
=ROUND(A1,2) // Round to 2 decimal places
=ROUND(A1,3) // Round to 3 decimal places
=ROUND(A1,4) // Round to 4 decimal places
``````

### Round to left

To round down values to the left of the decimal point, use zero or a negative number for digits:

``````=ROUND(A1,0) // Round to nearest whole number
=ROUND(A1,-1) // Round to nearest 10
=ROUND(A1,-2) // Round to nearest 100
=ROUND(A1,-3) // Round to nearest 1000
=ROUND(A1,-4) // Round to nearest 10000
``````

### Nesting inside ROUND

Other operations and functions can be nested inside the ROUND function. For example, to round down the result of A1 divided by B1, you can ROUND in a formula like this:

``````=ROUND(A1/B1,0) // round result to nearest integer
``````

Any formula that returns a numeric result can be nested inside the ROUND function.

### Other rounding functions

Excel provides a number of rounding functions, each with a different behavior:

### Notes

• The ROUND function rounds to a specified level of precision, determined by num_digits.
• If number is already rounded to the given number of places, no rounding occurs.
• If number is not numeric, ROUND returns a #VALUE! error. Author ### Dave Bruns
