float
| size_t offset, |
const __constant half *p) |
Description
Read sizeof(half bytes of data from address (n)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 read address computed as (p + (offset * n)) must be 16-bit aligned.
Notes
Vector Data Load and Store Functions allow you to read and write vector types from a pointer to memory.
The results of vector data load and store functions are undefined if the address being read from
or written to is not correctly aligned. The pointer argument p can be a
pointer to __global,
__local, or
__private memory
for store functions. The pointer argument p can be a pointer to
__global, __local, __constant
or __private memory for load functions.
vload3 and vload_half3 read x, y, z components from address (p + (offset * 3)) into a 3-component vector. vstore3, and vstore_half3 write x, y, z components from a 3-component vector to address (p + (offset * 3)).
In addition vloada_half3 reads x, y, z components from address (p + (offset * 4)) into a 3-
component vector and vstorea_half3 writes x, y, z components from a 3-component vector to
address (p + (offset * 4)).
