# Rem= Operator

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

## Syntax

```
variable Rem= expression
```

## Parts

`variable`

- A numeric variable or property.
`expression`

- A numeric expression.

## Instructions

The two statements that follow operate the same.

```
variable Rem= expression
variable = variable Rem expression
```

The element on the left side of `Rem=`

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`

.

Rem= 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.

`Rem`

does some of the same operations as `Rem=`

.
Thus, the sign of the variable or property (positive or negative) becomes the sign of the expression.
This is also where `Rem=`

is different from `Mod=`

.
`Mod=`

takes its sign from the variable or property.
