COT
A scalar numeric function that returns the cotangent, in radians, of an angle.
Synopsis
{fn COT(float-expression)}
Arguments
| float-expression | An expression of type FLOAT. This is an angle expressed in radians. |
Description
COT takes any nonzero number and returns its cotangent as a floating point number. COT returns NULL if passed a NULL value. A numeric value of 0 (zero) causes a runtime error, generating an SQLCODE -400 (fatal error occurred). COT treats nonnumeric strings as the numeric value 0.
COT returns a value of data type FLOAT with a precision of 36 and a scale of 18.
COT can only be used as an ODBC scalar function (with the curly brace syntax).
You can use the DEGREES function to convert radians to degrees. You can use the RADIANS function to convert degrees to radians.
Examples
The following examples show the effect of COT:
SELECT {fn COT(0.52)} AS Cotangent returns 1.74653.
SELECT {fn COT(124.1332)} AS Cotangent returns -0.040312.
