title: Round a float up to the next integer in javascript
body: <p>I need to round floating point numbers up to the nearest integer, even if the number after the point is less than 0.5.</p>
  
  <p>For example,</p>
  
  <ul>
  <li>4.3 should be 5 (not 4)  </li>
  <li>4.8 should be 5</li>
  </ul>
  
  <p>How can I do this in JavaScript?</p>
