title: Math round only up quarter
body: <pre><code>var number = 0.08;
  var newNumber = Math.round(number * 4) / 4 //round to nearest .25
  </code></pre>
  
  <p>With the code above i can round to nearest .25. However i only want it to round up. Whereby:</p>
  
  <pre><code>0.08 = 0.25
  0.22 = 0.25
  0.25 = 0.25
  0.28 = 0.5
  </code></pre>
  
  <p>How will that be possible?</p>
