sqrt (Function)
This function returns the square-root of the given value. It wraps the java.lang.Math.sqrt()
function.
Syntax
<DOUBLE> math:sqrt(<INT|LONG|FLOAT|DOUBLE> p1)
Query Parameters
Name | Description | Default Value | Possible Data Types | Optional | Dynamic |
---|---|---|---|---|---|
p1 | The value of the parameter whose square-root value should be found. | INT LONG FLOAT DOUBLE | No | Yes |
Example 1
CREATE STREAM InValueStream (inValue double);
@info(name = 'calculateSquareRoot')
INSERT INTO OutMediationStream
SELECT math:sqrt(inValue) AS sqrtValue
FROM InValueStream;
The calculateSquareRoot
query processes the input stream InValueStream
, which contains a single field inValue
. For each event in the input stream, the query calculates the square-root value of the inValue
using the math:sqrt()
function.
The math:sqrt()
function takes the given inValue
and returns the corresponding square-root value.
The calculated square-root value is aliased as sqrtValue
, and the output stream OutMediationStream
contains this value. This query processes the input stream events and forwards the resulting square-root values to the output stream for further processing or analysis.
For example, if inValue
is 4, the sqrtValue
will be 2.
