Units users,<br><br>How do I define an operator* which takes a quantity&lt;length&gt;,quantity&lt;length&gt; and returns a quantity&lt;area&gt;? This doesn&#39;t seem to be defined in the boost::units, which somewhat surprises me. How do we make something like that part of the core definition?<br>
<br>Thanks,<br><br>Michael<br>
