DEGREES
The DEGREES function returns the number of degrees of the argument, which is an angle, expressed in radians.
The schema is SYSIBM.
The argument must be an expression that returns the value of any built-in numeric data type that is not DECFLOAT. If the argument is not a double precision floating-point number, it is converted to one for processing by the function.
The result of the function is a double precision floating-point number.
The result can be null; if the argument is null, the result is the null value.
Example: Assume that host variable HRAD is a
DOUBLE with a value of 3.1415926536. The following statement returns
a double precision floating-point number with an approximate value
of 180.0.
SELECT DEGREES(:HRAD)
FROM SYSIBM.SYSDUMMY1;
