# `round`

## Description

Returns a number rounded to the nearest integer or to a specified number of decimal places. For example, `1.5` becomes `2` and `8.1` becomes `8`.

## Syntax

Like many functions in DataPrime, `round` supports<!-- --> [two notations](https://coralogix.com/docs/dataprime/language-reference/functions-reference.md),<!-- --> **function** and **method**. These interchangeable forms allow flexibility in how you structure expressions.

* Function notation
* Method notation

```
round(number: number, digits: number?): number
```

```
(number: number).round(digits: number?): number
```

## Arguments

| Name     | Type     | Required  | Description                                                           |
| -------- | -------- | --------- | --------------------------------------------------------------------- |
| `number` | `number` | **true**  | The value to round                                                    |
| `digits` | `number` | **false** | Number of decimal places to round to. Defaults to `0` (whole numbers) |

## Example

**Use case: Round averages for discrete counts**

Compute the average number of online users and round to a whole number for clarity. Example: `569.5` becomes `570`.

**Use case 2: Round latency values for readability**

When analyzing traces, average latency values may have long decimal places. Use `round` with `2` digits for cleaner results.

### Example data

```
{

    "total_users_online": 1093

},

{

    "total_users_online": 942

},

{

    "total_users_online": 120

},

{

    "total_users_online": 123

}
```

### Example query

* Function notation
* Method notation

```
aggregate round(avg(total_users_online)) as average_users_online
```

```
aggregate total_users_online.avg().round() as average_users_online
```

### Example output

```
{

    "average_users_online": 570

}
```
