Intel® Fortran Compiler 17.0 Developer Guide and Reference
Elemental Intrinsic Function (Generic): Produces the cosine of an argument.
result = COS (x)
x |
(Input) Must be of type real or complex. It must be in radians and is treated as modulo 2*pi. If x is of type complex, its real part is regarded as a value in radians. |
The result type and kind is the same as x.
