title: Exif Direction of Picture
body: <p>I have a bunch of Geotagged pictures that I'm accessing in python using pyexiv2. It's working great except I don't understand what the "GPSImgDirection" value is giving. Basically, it's two great big numbers, for example:</p>
  
  <p><code>2147483647/8613474</code></p>
  
  <p>What does that mean? I think it's a "rational" data type. What does that mean? How can I turn the number into something people could understand, such as "5 degrees East of North"?</p>
  
  <p>Thanks!
