## Purpose

## Return value

## Arguments

*number*- The number to round.*num_digits*- The place at which number should be rounded.

## Syntax

## Usage notes

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:

- To round with standard rules, use the ROUND function.
- To round to the nearest
*multiple*, use the MROUND function. - To round
*down*to the nearest specified*place*, use the ROUNDDOWN function. - To round
*down*to the nearest specified*multiple*, use the FLOOR function. - To round
*up*to the nearest specified*place*, use the ROUNDUP function. - To round
*up*to the nearest specified*multiple*, use the CEILING function. - To round
*down*and return an integer only, use the INT function. - To truncate decimal places, use the TRUNC function.

### 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.
