title: Convert rating percent (50%) to the equivelant 5-star rating in PHP
body: <p>I'm sure this is possible but my math isn't that fantastic.</p>
  
  <p>I'm showing latest movies on my page and my application uses a 5-star rating system, however, the data I receive from a Web Service arrives as a percentage e.g. 50%.</p>
  
  <p>Is there any way I can convert this percentage to a star rating equivalent, which in this case would be 50% = 2.5, allowing me to show 2.5 stars?</p>
  
  <p>It seems fairly simple when I have 50% but if I get 94%, it confuses my poor little pea for a brain! Please help.</p>
