 * This was created to pass in screen ratios like 3440 / 1440 and get rounded value for comparison.
 * You have to adjust the decimals depending on if it's landscape or portrait to be able to do a comparison.
 * That way you can group screen sizes in buckets like 16 x 9 when the actual ratio is fractionally different
