`Mod=`

Operator

Divides the value of a variable by the value of an expression, then changes the variable to the remainder.

## Syntax

```
variable Mod= expression
```

## Parts

`variable`

- A numeric variable or property.
`expression`

- A numeric expression.

## Instructions

The two statements that follow operate the same.

```
variable Mod= expression
variable = variable Mod expression
```

The element on the left side of `Mod=`

can be a scalar variable, a property, or an element of an array.
If it is a property, then it cannot have the modifier `@ReadOnly`

.

`Mod=`

divides the variable or property on its left side by the value on its right side to get a quotient and a remainder.
Then it changes the variable or property on its left side to the remainder.

`Mod`

does some of the same operations as `Mod=`

.
Thus, the sign of the variable or property (positive or negative) does not change.
This is also where `Mod=`

is different from `Rem=`

.
`Rem=`

takes its sign from the expression.

## Examples

```
x = 42
x Mod= 10
y = 24
y Mod= -10
```

variable | value |
---|---|

`x` | 2 |

`y` | -4 |
