title: How to round off seconds to the nearest minute?
body: <p>I am converting [ss] seconds to mm:ss format.<br>
  But, I also have to round off the value to the nearest minute.<br>
  For example, 19:29 -> 19 minutes and 19:32-> 20 minutes</p>
  
  <p>I have tried using <code>mround</code> function. But it did not work.  </p>
  
  <pre><code>=MROUND(19.45,15/60/24) gives output as 19.44791667.  
  </code></pre>
  
  <p>It should come as 20 seconds.</p>
