title: JavaScript Number preserve leading 0
body: <p>I have a problem, I build a very simple javascript search for postal codes.
  I am using JS Numbers because I want to check if the passed number (search term) is less||equal or more||equal to the max and min.</p>
  
  <pre><code>value &gt;= splitZips[0] &amp;&amp; value &lt;= splitZips[1]
  </code></pre>
  
  <p>But the Javascript Number var type deletes leading 0, which is a problem because I have postal codes like 01075 and also postal codes like 8430. So it can not find the small 4 digit codes.</p>
  
  <p>Any idea how to fix this?</p>
