exp (Function)
This function returns the Euler's number e raised to the power of p1. It wraps the java.lang.Math.exp() function.
Syntax
<DOUBLE> math:exp(<INT|LONG|FLOAT|DOUBLE> p1)
Query Parameters
| Name | Description | Default Value | Possible Data Types | Optional | Dynamic |
|---|---|---|---|---|---|
| p1 | The power that the Euler's number e is raised to. | INT LONG FLOAT DOUBLE | No | Yes |
Example 1
CREATE STREAM InValueStream (inValue double);
insert into OutMediationStream
select math:exp(inValue) as expValue
from InValueStream;
If the inValue in the inputstream holds a value, this function calculates the corresponding Euler's number e and directs it to the output stream, OutMediationStream. For example, exp(10.23) returns 27722.51006805505.
