<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<p>Relational and equality operators (&lt;, &lt;=, &gt;, &gt;=, ==, !=) are defined to operate on scalars and produce scalar Boolean results. </p>
<p>For vector results, use the following built-in functions.</p>
<p>In all cases, the sizes of all the input and return vectors for any particular call must match. </p>
