PHP: power bug - 10^(1/4) == 10?
<p>Why 10^(1/4) is 10? which function should I use to obtain correct result?  </p>

<p>My test line is:</p>

<pre><code> echo (10^(100/400)). " vs " . 10;
</code></pre>

<p>and my output is</p>

<pre><code>10 vs 10
</code></pre>

<p>EDIT:</p>

<p>thanks for answers, I will use pow()</p>
