<h2>Description</h2>
<p>
<code class="function">mad24</code> multiplies two 24-bit integer values <code class="varname">x</code> and <code class="varname">y</code> and add the 32-bit integer result to the 32-bit integer <code class="varname">z</code>. See <a class="citerefentry" href="mul24.html"><span class="citerefentry"><span class="refentrytitle">mul24</span></span></a> to see how the 24-bit integer multiplication is performed.

<h2>Notes</h2>
<p>
Fast integer functions can be used for optimizing performance of
kernels. We use the generic type name <span class="type">gentype</span> to indicate that the function can take <span class="type">int</span>,
<code class="constant">int2</code>, <code class="constant">int4</code>, <code class="constant">int8</code>, <code class="constant">int16</code>, <span class="type">uint</span>, <code class="constant">uint2</code>, <code class="constant">uint4</code>, <code class="constant">uint8</code>, or <code class="constant">uint16</code> as the
type for the arguments.
