MathPow Class

public final class MathPow
extends `MathOperator`

Power of operator.
Input 1: A `Number` (or expression returning a `Number`) that is LHS of the operator.
Input 2: A `Number` (or expression returning a `Number`) that is RHS of the operator.
Returns: A `Number`: `java.lang.Math.pow( LHS, RHS )`.

## Method Detail

### getLeftHandSide() Method

    public Object getLeftHandSide()

Description copied from `BinaryOperator.getLeftHandSide()`
Returns left hand side operand of this binary operator.

#### Returns

The left hand side operand.

### getParameterSignature() Method

    public Class[] getParameterSignature()

Description copied from `Expression.getParameterSignature()`
Returns the parameter signature for this `Expression`. Because the sub-expressions within the `Expression` are typically arguments or operands, some type validation is performed by examining the class types of the sub-expressions against the `Expression`'s parameter signature.
The tests that are performed are:
1. The number of sub-expressions must equals the number of parameter entries.
2. The class type of any sub-expression (or the result of evaluating the sub-expresssion) must equal the class type of the corresponding parameter entry.
3. Any null parameter entries are ignored and are considered optional sub-expressions.

#### Returns

the Class array containing the parameter signature.

### getRightHandSide() Method

    public Object getRightHandSide()

Description copied from `BinaryOperator.getRightHandSide()`
Returns right hand side operand of this binary operator.

#### Returns

The left hand side operand.
