vload_halfn

Read a half float vector from a pointer to memory.

floatn vload_halfn ( size_t offset,
  const __global half *p)
floatn vload_halfn ( size_t offset,
  const __local half *p)
floatn vload_halfn ( size_t offset,
  const __constant half *p)
floatn vload_halfn ( size_t offset,
  const __private half *p)

Description

Returns sizeof(floatn) bytes of data read from location (p + (offset * n)).

The half value read is converted to single precision floating-point. The read address computed as (p + (offset * n)) must be 16-bit aligned.
