title: Calculating The Percentage Change Between Two Numbers
body: <p>Looking for some clarification on below code for calculating the percentage change between two different number of which the original could be a greater or smaller number. So will this code work for showing either a increase + or a decrease - change? Thanks.</p>
  
  <pre><code>$original= 100;

  $percentChange = (1 - $original / $current ) * 100;
  </code></pre>
