title: How to change font in the string only for the last two characters
body: <p>I have the string 0.1234
  To find the last two characters I use string.suffix(2)
  if I use NSRange to find this range in attributedString it works well until the string will not be with equals values. if the string would be like 1.1212, nsrange will be applied to the first found value (string.suffix(2) = 12 in this case)
  so the formatting will be wrong. </p>
