Description
Read sizeof(half) bytes of data from address (p + offset). The data read is interpreted as a half value.
The half value is converted to a float value and the float value is returned. The read address computed
as (p + offset) must be 16-bit aligned.
An application that wants to use half and halfn types will need to include the #pragma OPENCL EXTENSION
cl_khr_fp16(3clc) : enable directive.
