issue with adding decimal point in front of an int
<p>So I am trying to add a decimal point in front of a whole in (10)  The issue is I'm trying to use <code>sprintf();</code> but it seems to not be working for me :(. </p>

<p>Code:</p>

<pre><code>sprintf(".",($percentamount));
</code></pre>

<p>Let me know what I am doing wrong thanks!</p>

<p>I have already tried <code>"%.f"</code></p>
