title: Include literal % percent sign in printf formatting string
body: <p>Here is my code:</p>
  
  <pre><code>&lt;?php printf( __( '%.0f' ), $mini_deck-&gt;rating_per.'%' ); ?&gt;
  </code></pre>
  
  <p>My problem is that the "rating_per" percentage sign (%) isn't showing after the percentage number on my website. What's wrong in my code?</p>
