COS
Elemental Intrinsic Function (Generic): Produces the cosine of an argument in radians.
result = COS (x)
x  |  
      (Input) Must be of type real or complex. It must be in radians and is treated as modulo 2*pi.  |  
     
Results
The result type and kind are the same as x.
If x is of type real, the result is a value in radians.
If x is of type complex, the real part of the result is a value in radians.
