        <p>
            The built-in relational functions can be used with built-in scalar or vector types as 
            arguments and return a scalar or vector integer result. If an implementation extends this 
            specification to support IEEE-754 flags or exceptions, then all built-in Relational

            of functions that take <span class="type">half</span>, and <span class="type">half{2|3|4|8|16}</span> as arguments and return values. 
            The relational and equality operators (&lt;, &lt;=, &gt;, &gt;=, !=, ==) can be used 
            with <span class="type">double<em class="replaceable"><code>n</code></em></span> vector types and shall produce a vector

            The function returns a 0 if the specified relation is <code class="constant">false</code> and a

            functions shall return a 0 if the specified relation is <code class="constant">false</code> and a - 1
