        <p>Built-in geometric functions operate component-wise and the description is per-component. The generic type name <span class="type">gentype</span> indicates that the
function can take <span class="type">float</span>, <span class="type">float2</span>, or <span class="type">float4</span> as the type for the arguments.</p>
        <p>The built-in geometric functions are implemented using the round to nearest even rounding mode.

        <p>The geometric functions can be implemented using contractions such as <a class="citerefentry" href="mad.html"><span class="citerefentry"><span class="refentrytitle">mad</span></span></a> or <a class="citerefentry" href="fma.html"><span class="citerefentry"><span class="refentrytitle">fma</span></span></a>.</p>
