Casting zero padded numeric strings to integers
<p>I am padding integers for barcodes with leading zeros so they have same number of characters, for example:</p>

<pre>
1    -> 00000001 
12   -> 00000012
1044 -> 00001044
</pre>

<p><code>00000001</code> is numeric and when casting to an integer it is <code>1</code>. </p>

<p>Will this work as expected for <strong>all</strong> integers?</p>
