<div class="paragraph">
<p>The following table describes the list of supported functions that allow you
to read and write vector types from a pointer to memory.
We use the generic type <code>gentype</code> to indicate the built-in data types
<code>char</code>, <code>uchar</code>, <code>short</code>, <code>ushort</code>, <code>int</code>, <code>uint</code>, <code>long</code>, <code>ulong</code>, <code>float</code>
or <code>double</code>.
We use the generic type name <code>gentype<em>n</em></code> to represent n-element vectors
of <code>gentype</code> elements.
We use the type name <code>half<em>n</em></code> to represent n-element vectors of half
elements<sup>37</sup>.
The suffix <em>n</em> is also used in the function names (i.e. <strong>vload<em>n</em></strong>,
<strong>vstore<em>n</em></strong> etc.), where <em>n</em> = 2, 3, 4, 8 or 16.</p>
</div>
<div class="paragraph">
<p>[37] The <code>half<em>n</em></code> type is only defined by the <strong>cl_khr_fp16</strong> extension
described in <a href="https://www.khronos.org/registry/OpenCL/specs/2.2/html/OpenCL_C.html#opencl-extension-spec" target="_blank" rel="noopener">section 9.4 of the OpenCL 2.0 Extension
