cos is the cosine function.

       cosh is the hyperbolic cosine function.

       cospi computes cos (x * pi).

       half_cos computes cosine.  x must be in the range -216... +216. This function is implemented with a
       minimum of 10-bits of accuracy i.e. an ULP value less than or equal to 8192 ulp.

       native_cos computes cosine over an implementation-defined range. The maximum error is
       implementation-defined. Functions with the native__ prefix may map to one or more native device
       instructions and will typically have better performance compared to the corresponding functions (without
       the native__ prefix). The accuracy (and in some cases the input range(s)) of these functions is
       implementation-defined.
