# Less or Equal

### Description

Checks whether first argument is less or equal than the second argument.

### any <= any

```java
Scalar<any> <= Scalar<any> : Scalar<Boolean>
Scalar<any> <= GroupedScalar<any> : GroupedScalar<Boolean>
GroupedScalar<any> <= Scalar<any> : GroupedScalar<Boolean>
GroupedScalar<any> <= GroupedScalar<any> : GroupedScalar<Boolean>
```

Comparing if a Scalar\<any> is less or equal than another Scalar\<any>. Returns a Scalar\<Boolean> either true if the first operator is less or equal than the second otherwise false.

If one argument is a Scalar, and the other one a GroupedScalar, then the operation is performed by taking the Scalar value and the value of each group value, which results another GroupedScalar (it has same group size, as the one from the input argument).

If both arguments are GroupedScalar, then the operation is performed by taking values with same group key, which  results in another Grouped Scalar (the group size is equal or smaller than the ones of the input arguments).

### Examples

Check if the PowerConsumption is less or equals than the PowerProduction

```java
$PowerConsumption <= $PowerProduction
```
