<h2>Description</h2>
<p>
Returns the component-wise compare of <code class="varname">x</code> &gt; <code class="varname">y</code>.

</div>
<div class="refsect1">
<a id="notes"></a>
<h2>Notes</h2>
<p>
If an implementation extends this specification to support IEEE-754 flags or
exceptions, then all built-in relational functions shall proceed without raising the
<code class="varname">invalid</code> floating-point exception when one or more of the operands
are NaNs.
</p>
<p>
The built-in relational functions are extended with
<a class="citerefentry" href="cl_khr_fp16.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_fp16</span></span></a> to
include versions that take <span class="type">half</span>, and
<span class="type">half{2|3|4|8|16}</span> as arguments.
</p>
<p>
The function returns a 0 if the specified relation is <code class="constant">false</code> and a 1
if the specified relation is <code class="constant">true</code> for scalar argument types. These
functions shall return a 0 if the specified relation is <code class="constant">false</code> and a -
1 (i.e. all bits set) if the specified relation is <code class="constant">true</code> for vector
argument types.
</p>
<p>
The function returns 0 if either argument is not a number (NaN).
