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);
@info(name = 'getExponentValue')
INSERT INTO OutMediationStream
SELECT math:getExponent(inValue) AS expValue
FROM InValueStream;
The query calculates the unbiased exponent of a given input, inValue, from the InValueStream using the math:getExponent() function. The result is directed to the output stream OutMediationStream. For example, getExponent(60984.1) returns 15.
