title: jQuery regular expression for decimal [17, 2]
body: <p>I'd like to check number what it is decimal [17, 2] (0~17 and 0~2).</p>
  
  <p>What is the regular expression for a decimal [17,2]?</p>
  
  <p>For example</p>
  
  <pre><code>1
  0.01
  0.1
  12345678901234567.01
  ...
  </code></pre>
  
  <p>I used <code>var regexp = /^\d+(?:\.\d\d?)?$/;</code> but it can be over 17.</p>
