title: Calculating Percentage Change returns 0
body: <p>I tried to find the percentage change of a <code>float</code>, however the query returns <code>0.00</code></p>
  
  <pre><code>SELECT CAST(((SELECT 115301-(SELECT 114256))/(SELECT 114256))*100 AS DECIMAL(18,2))
  </code></pre>
  
  <p>Is there anything that I miss here? Where should I edit the SQL?</p>
