power (Function)
This function raises the given value to a given power.
Syntax
<DOUBLE> math:power(<INT|LONG|FLOAT|DOUBLE> value, <INT|LONG|FLOAT|DOUBLE> to.power)
Query Parameters
| Name | Description | Default Value | Possible Data Types | Optional | Dynamic |
|---|---|---|---|---|---|
| value | The value that should be raised to the power of to.power input parameter. | INT LONG FLOAT DOUBLE | No | Yes | |
| to.power | The power to which the value input parameter should be raised. | INT LONG FLOAT DOUBLE | No | Yes |
Example 1
CREATE STREAM InValueStream (inValue1 double, inValue2 double);
@info(name = 'calculatePower')
INSERT INTO OutMediationStream
SELECT math:power(inValue1, inValue2) AS powerValue
FROM InValueStream;
The calculatePower query processes the input stream InValueStream, which contains two fields, inValue1 and inValue2. For each event in the input stream, the query calculates the result of raising inValue1 to the power of inValue2 using the math:power(inValue1, inValue2) function.
The calculated power value is aliased as powerValue and directed to the OutMediationStream. This query processes the input stream events and forwards the result of the power operation to the output stream for further processing or analysis. For example, power(5.6d, 3.0d) returns 175.61599999999996.
