title: Javascript Ceil Increments
body: <p>I currently have this which rounds up any input number to the nearest whole value on blur:</p>
  
  <pre><code>$(function(){
      $('#my_value').blur(function() {
      $(this).val(Math.ceil($(this).val()));
      });
  });
  </code></pre>
  
  <p>The problem is I need it to round to the next nearest 1/10th, so if someone input 1.23 it would round up to 1.3. Or if someone input 3.78 it would round up to 3.8.</p>
  
  <p>Additionally I'd like it to display an alert when a value above 9 is entered into the #my_value field.</p>
  
  <p>Thanks in advance.</p>
