Power: power

Syntax

power ( base , exponent )

Input parameters

base	the operand
exponent	the exponent of the power

Examples of valid syntaxes

power ( DS_1, 2 )
power ( 5, 2 )

Semantics for scalar operations

The operator power raises a number (the base) to another one (the exponent). For example:

power ( 5, 2 ) gives 25
power ( 5, 1 ) gives 5
power ( 5, 0 ) gives 1
power ( 5, -1 ) gives 0.2
power ( -5, 3 ) gives -125

Input parameters type

base

dataset { measure<number> _+ }
| component<number>
| number

exponent

component<number>
| number

Result type

result

dataset { measure<number> _+ }
| component<number>
| number

Additional Constraints

None.

Behaviour

As for the invocations at Data Set level, the operator has the behaviour of the “Operators applicable on one Scalar Value or Data Set or Data Set Component”. As for the invocations at Component or Scalar level, the operator has the behaviour of the “Operators applicable on two Scalar Values or Data Sets or Data Set Components”, (see the section “Typical behaviours of the ML Operators”). According to the general rules about data types, the operator can be applied also on sub-types of number, that is the type integer. The result has type number.
