title: Round a divided number in Bash
body: <p>How would I round the result from two divided numbers, e.g.</p>
  
  <pre><code>3/2
  </code></pre>
  
  <p>As when I do </p>
  
  <pre><code>testOne=$((3/2))
  </code></pre>
  
  <p>$testOne contains "1" when it should have rounded up to "2" as the answer from 3/2=1.5</p>
