vloada_halfn Read half float vector from a pointer to memory.

floatn `vloada_halfn` size_t offset const __global half*p floatn `vloada_halfn` size_t offset const __local half*p floatn `vloada_halfn` size_t offset const __constant half*p floatn `vloada_halfn` size_t offset const __private half*p

## Description

For n = 1, 2, 4, 8 and 16 read sizeof(halfn) bytes of data from address (`p` + (`offset` * `n`)). The data read is interpreted as a halfn value. The halfn value read is converted to a floatn value and the floatn value is returned.

The address computed as (`p` + (`offset` * `n`)) must be aligned to sizeof(halfn) bytes.

For n = 3, `vloada_half3` reads a half3 from address (`p` + (`offset` * 4)) and returns a float3. The address computed as (`p` + (`offset` * 4)) must be aligned to sizeof (half) * 4 bytes.

## Notes

&vectorFunctionsInc;

In addition `vloada_half3` reads `x`, `y`, `z` components from address (`p` + (`offset` * 4)) into a 3- component vector.
