## Purpose

## Return value

## Arguments

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

## Syntax

## Usage notes

The ROUNDUP function rounds numbers *up*. Unlike standard rounding, where only numbers less than 5 are rounded down, ROUNDUP rounds *all numbers up*. For example:

```
=ROUNDUP(3.1,0) // returns 4
```

ROUNDUP 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 ROUNDUP function rounds on the *right* side of the decimal point. When *num_digits* is less or equal to zero, the ROUNDUP function rounds on the *left* side of the decimal point. Use zero (0) for *num_digits* to round to the nearest integer. The table below summarizes this behavior:

Digits | Behavior |
---|---|

>0 | Round up to nearest .1, .01, .001, etc. |

<0 | Round up to nearest 10, 100, 1000, etc. |

=0 | Round up to nearest 1 |

### Round to right of decimal

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

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

### Round to left of decimal

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

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

### Nesting inside ROUNDUP

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

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

### 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.
