       The vector versions of the math functions operate component-wise. The description is

       The built-in math functions are not affected by the prevailing rounding mode in the
       calling environment, and always return the same value as they would if called with the
       round to nearest even rounding mode.

       The built-in math functions take scalar or vector arguments. The generic type name gentype
       is used to indicate that the function can take float, float2, float3, float4, float8, or
       float16 as the type for the arguments. For any specific use of these function, the actual
       type has to be the same for all arguments and the return type.

       If extended with cl_khr_fp16(3clc), generic type name gentype may indicate half and
       half{2|3|4|8|16} as arguments and return values.
