## Syntax

```
Mod(dividend, divisor)
```

The `Mod()` function has two parameters:

- `dividend` (number): Required. The initial number.
- `divisor` (number): Required. The number to divide the dividend by.

## Usage

To use this function, pass it two numbers. The numbers can be positive or negative integer or decimal numbers.

```
%%=Mod(500,12)=%%
```

The function returns the modulus of the two numbers: `8` (500 divided by 12 is 41 with a remainder of 8).

This function also works with decimal and negative numbers.

```
%%=Mod(-500.123,12.456)=%%
```

This example returns the remainder: `-1.88300000000001`.
