SIN calculates the sine of a real number in radians.

Declaration 

        FUNCTION SIN(VAR x:REAL):REAL; EXTERNAL;

Attributes 

Parameter:                A real number in radians.

Result:                   A representable real number in the range [-1.0,
                          1.0].  See Chapter 1 for details on the
                          internal representation of real numbers.

HP FORTRAN 77/XL:         Intrinsic function:  Y=SIN(X).

Error:                    If the argument is a NaN or an Infinity, there
                          are two possible actions.  If the INVALID trap
                          is enabled, the message "SIN(X): X=NaN OR
                          INFINITY" occurs.  Otherwise, the INVALID flag
                          is set.  In either case, a quiet NaN is
                          returned.
