Finding the number of places after the decimal point of a Double
<p>I have a Double value:</p>

<pre><code>double a = 4.5565;
</code></pre>

<p>What is the easiest way to calculate the number of digits after the decimal point (4 in this case).</p>

<p>I know that I can convert to string and do a split and take the length. But is there an easier way?</p>
