Php weird rounding
<p>Simple question: Why this behavior:</p>

<pre><code>var_dump($calc_product);
var_dump($calc_price);
var_dump(round($calc_product,1));
var_dump(round($calc_price,1));
</code></pre>

<p>gives:</p>

<pre><code>float(16.05) float(16.05) float(16) float(16.1)
</code></pre>

<p>Thanks!</p>
