p><code class="code">fma&nbsp;x&nbsp;y&nbsp;z</code> returns <code class="code">x&nbsp;*&nbsp;y&nbsp;+&nbsp;z</code>, with a best effort for computing
   this expression with a single rounding, using either hardware
   instructions (providing full IEEE compliance) or a software
   emulation.  Note: since software emulation of the fma is costly,
   make sure that you are using hardware fma support if performance
   matters.</p>
