title: How to extract Hours and Minutes (from Date) as a number in Oracle?
body: <p>What I did:</p>
  
  <pre><code>SELECT TO_CHAR(SYSDATE, 'HH24:MI') FROM dual;
  </code></pre>
  
  <p>What i got:</p>
  
  <pre><code>13:30
  </code></pre>
  
  <p>What I want :</p>
  
  <pre><code>13.50
  </code></pre>
  
  <p>I also tried the EXTRACT function then summed hours and minutes but still not working. </p>
