vload_half Read a half float from a pointer to memory.

##

float `vload_half` size_t offset const __global half*p float `vload_half` size_t offset const __local half*p float `vload_half` size_t offset const __constant half*p float `vload_half` size_t offset const __private half*p

## 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 : enable` directive.
