title: prometheus number of pod restarts not an integer
body: <p>I am trying to understand why prometheus is displaying the number of restarts as a decimal. If I have a query like: <code>delta(kube_pod_container_status_restarts_total[2d]) &gt;= 1</code> which shows number of restarts over a long duration the result is:</p>
  <pre><code>value
  11.135802469135804
  2.0408163265306123
  2.2
  </code></pre>
  <p>3 pods restarted 1 or more times in the last 2 days. However they restarted a non-integer amount of times? Increasing the duration out further to 4 days doesnt change the values.</p>
