Description
The floatn (or doublen if optional double is supported) value igiven by data is converted to a halfn
value using the appropriate rounding mode.
For n = 1, 2, 4, 8 and 16, the halfn value is written to the address computed as (p + (offset * n)). The
address computed as (p + (offset * n)) must be aligned to sizeof (halfn) bytes.
For n = 3, the half3 value is written to the address computed as (p + (offset * 4)). The address computed
as (p + (offset * 4)) must be aligned to sizeof (half) * 4 bytes.
vstorea_halfn uses the default rounding mode. The default rounding mode is round to the nearest even.
An application that wants to use half and halfn types will need to include the #pragma OPENCL EXTENSION
cl_khr_fp16(3clc) : enable directive.

If the optional double is supported, you may use doublen
instead of floatn.
