# `mod`

## Description

Returns the remainder after dividing a number by a divisor. Equivalent to the modulus operator (`%`).

## Syntax

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

* Function notation
* Method notation

```
mod(number: number, divisor: number): number
```

```
(number: number).mod(divisor: number): number
```

## Arguments

| Name      | Type     | Required | Description                                |
| --------- | -------- | -------- | ------------------------------------------ |
| `number`  | `number` | **true** | The value to divide                        |
| `divisor` | `number` | **true** | The divisor used for the modulus operation |

## Example

**Use case: Determine if a number is even or odd**

A value is even if dividing it by `2` leaves a remainder of `0`. Otherwise, it is odd.

### Example data

```
{

    "val": 7

},

{

    "val": 12

}
```

### Example query

* Function notation
* Method notation

```
create is_even from (mod(val, 2) == 0)
```

```
create is_even from (val.mod(2) == 0)
```

### Example output

```
{

    "val": 7,

    "is_even": false

},

{

    "val": 12,

    "is_even": true

}
```
