cos (Function)
This function returns the cosine of p1
which is in radians. It wraps the java.lang.Math.cos()
function.
Syntax
<DOUBLE> math:cos(<INT|LONG|FLOAT|DOUBLE> p1)
Query Parameters
Name | Description | Default Value | Possible Data Types | Optional | Dynamic |
---|---|---|---|---|---|
p1 | The value of the parameter whose cosine value should be found.The input is required to be in radians. | INT LONG FLOAT DOUBLE | No | Yes |
Example 1
CREATE STREAM InValueStream (inValue double);
@info(name = 'cosineValues')
INSERT INTO OutMediationStream
SELECT math:cos(inValue) AS cosValue
FROM InValueStream;
The query takes the input value inValue
from the InValueStream
and calculates the cosine value using the math:cos()
function. The result is directed to the output stream OutMediationStream
. For example, when inValue
is 6, the cosValue
returned is 0.9601702866503661.
