  console.log(n2f('3em'))            // => 3/1
  console.log(n2f('1.5px'))          // => 3/2
  console.log(n2f(7 / 9)             // => 7/9
  console.log(n2f(8 / 9)             // => 8/9
  console.log(n2f(512 / 999)         // => 512/999
  console.log(n2f((2 * π / 3) / π)   // => 2/3
  console.log(n2f((8 * 5) / (4 / 2)) // => 20/1

Example

Opera old versions support the non-standard -o-min-device-pixel-ratio or -o-max-device-pixel-ratio in CSS media queries.
