title: integer rounding with parseInt in javascript
body: <p>I have the following javascript code. </p>
  
  <pre><code>if( frequencyValue &lt;= 30)
              leftVal = 1;
          else if (frequencyValue &gt; 270)
              leftVal= 10;
          else 
              leftVal = parseInt(frequencyValue/30);
  </code></pre>
  
  <p>Currently if given the value 55 (for example) it will return 1 since 1&lt; 55/30 &lt; 2. I was wondering if there was a way to round up to 2 if the decimal place being dropped was greater than .5. </p>
  
  <p>thanks in advance</p>
