<p>Thanks! Useful addition, it is going to be merge.</p>
<p>One aspect to be sorted out: I think <code>-lm</code> needs to be linked now for the module, because you include <code>math.h</code>. It is part of libc standard library project, so no extra package dependency, but a different lib file <code>libm.so</code>.</p>
<p>Maybe on some systems works without explicit linking, but I know some complain. It just needs in the Makefile of the module:</p>
<pre><code>LIBS = -lm
</code></pre>
<p>Few other modules do it already. This can be an additional commit.</p>
