title: Invalidating zero in front of the currency regex
body: <p>So far I can validate currency up to certain point but there is a problem.</p>
  
  <p>My current regex: <code>/^[0-9]\d{0,7}+\.?\d{2}$/</code></p>
  
  <p>These should not be validated (This is what I cannot implement). <strong>No zero(s) in front accepted, unless it is like 0.50, 0.15 etc.</strong></p>
  
  <pre><code>0123456.00
  0123.55
  </code></pre>
  
  <p><strong>Validity rule:</strong></p>
  
  <ul>
  <li>Before dot sign: Max 8 numerics.</li>
  <li>After dot: 2 numerics compulsory.</li>
  <li>Dot is compulsory too.</li>
  </ul>
  
  <p><strong>So all these are valid:</strong></p>
  
  <pre><code>0.00
  0.10
  1.00
  12345678.00
  </code></pre>
