# NOT

### Description

Checks whether argument is not *true*.

### NOT Boolean

```java
NOT Scalar<Boolean> : Scalar<Boolean>
NOT Vector<Boolean> : Vector<Boolean>
NOT GroupedScalar<Boolean> : GroupedScalar<Boolean>
NOT GroupedVector<Boolean> : GroupedVector<Boolean>
```

Negate the Scalar\<Boolean> after the NOT keyword. This means a Scalar\<Boolean> with value true will return false and vise versa.

If it is a Vector, GroupedScalar or GroupedVector, then the operation is performed on each value, and results in another Vector, GroupedScalar or GroupedVector.

### Examples

Check if the PowerConsumption is NOT greater than the PowerProduction.

```java
NOT ($PowerConsumption > $PowerProduction)
```
