how to remove the numbers and keep the rest after the dot
<p>Sorry I couldn't explain clearly in the title. I Studied math in other language I don't know what it calls.</p>

<p>I have these values.</p>

<pre><code>$input = 13.2156;
$input = 45.232;
$input = 1193.215624;
</code></pre>

<p>I want a function in PHP to get what what after the dot,
which is this case</p>

<pre><code>$input = 13.2156;     // 0.2156
$input = 45.232;      // 0.232
$input = 1193.215624; // 0.215624
</code></pre>

<p>I know <code>intval()</code> do the opposite. <strong>BUT</strong> I want the opposite of the opposite. :D</p>
