RADIANS
The RADIANS function returns the number of radians for an argument that is expressed in degrees.
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 HDEG is
an INTEGER with a value of 180. The following statement returns a
double precision floating-point number with an approximate value of
3.1415926536.
SELECT RADIANS(:HDEG)
FROM SYSIBM.SYSDUMMY1;
