title: How do I print the '%' character with 'printf'?
body: <p>Simple problem that I can't figure out...</p>
  
  <p>How can I print a '%' character within a <code>printf</code> string? The code below prints it, but gives an 'invalid conversion' error as well.</p>
  
  <pre><code>printf "\t\t".$hour."00 HRS\t=&gt;\t%.2f\t%.2f\t%.1f\%\n", $total, $max15, ($max15/$total*100);
  </code></pre>
  
  <p>Should output something like:</p>
  
  <pre><code>        0000 HRS    =&gt;    3125.19    898.02    28.7%
  </code></pre>
