getExponent (Function)
This function returns the unbiased exponent that is used in the representation of p1. This function wraps the java.lang.Math.getExponent() function.
Syntax
<INT> math:getExponent(<INT|LONG|FLOAT|DOUBLE> p1)
Query Parameters
| Name | Description | Default Value | Possible Data Types | Optional | Dynamic |
|---|---|---|---|---|---|
| p1 | The value of whose unbiased exponent representation should be found. | INT LONG FLOAT DOUBLE | No | Yes |
Example 1
CREATE STREAM InValueStream (inValue double);
insert into OutMediationStream
select math:getExponent(inValue) as expValue
from InValueStream;
This function calculates the unbiased exponent of a given input, inValue and directs the result to the OutMediationStream output stream. For example, getExponent(60984.1) returns 15.
