The RADIANS function returns the number of radians for an argument that is expressed in degrees.
If the data type of the argument is DECFLOAT(n), the result is DECFLOAT(n). Otherwise, the data type of the result is double-precision floating point. If the argument can be null, the result can be null; if the argument is null, the result is the null value.
SELECT RADIANS(:HDEG) FROM SYSIBM.SYSDUMMY1Returns a double precision floating-point number with an approximate value of 3.1415926536.
