Cos                      Returns the Cosine of an Angle

 Cos(Angle : Real) : Real;
 Cos(Angle : Integer) : Real;

    Returns the cosine of Angle, which is in radians (2*Pi radians = 360
    degrees).

           Angle    An integer or real value (constant, variable, function
                    call, or expression).

         Limits:    none
