title: decimal numbers validation fail
body: <p>I should create a regular expression that match all following values.. these values are percentages, so max value is 100:</p>
  
  <ul>
  <li><code>1</code></li>
  <li><code>1.</code></li>
  <li><code>1.11</code></li>
  </ul>
  
  <p>I do not manage to match "<code>1.</code>". </p>
  
  <p>I have tried different regular expression... but with no success... I think the one nearest to the solution is </p>
  
  <pre><code>(\d{1,2})|((\d{1,2})(\.)?((\d{1,5})?))
  </code></pre>
  
  <p>But it still does not work...</p>
  
  <p>Does anyone can help me please?</p>
