Example 1
CREATE STREAM InValueStream (inValue double);
@info(name = 'calculateAbsoluteValue')
INSERT INTO OutMediationStream
SELECT math:abs(inValue) AS absValue
FROM InValueStream;
The query calculates the absolute value of the inValue from the input stream InValueStream using the math:abs() function. Regardless of whether the inValue is 3 or -3, the function returns 3, because the absolute value of both 3 and -3 is 3. The result is then directed to the OutMediationStream.
