Class Reference   

A numeric function that converts degrees to radians.
numeric-expression The measure of an angle in degrees. An expression that resolves to a numeric value.
RADIANS takes an angle measurement in degrees and returns the corresponding angle measurement in radians. RADIANS returns NULL if passed a NULL value.
The returned data type is NUMERIC unless numeric-expression is data type DOUBLE, in which case the returned data type is DOUBLE. The default precision is 36. The default scale is 18.
You can use the DEGREES function to convert radians to degrees.
The following Embedded SQL example returns the radians equivalents corresponding to the degree values from 0 through 365 in 30-degree increments:
   SET a=0
   WHILE a<366 {
   &sql(SELECT RADIANS(:a) INTO :b)
   IF SQLCODE'=0 {
     WRITE !,"Error code ",SQLCODE
     QUIT }
   ELSE {
     WRITE !,"degrees ",a," = radians ",b
     SET a=a+30 }
