title: Internationalization on percentage formatting
body: <p>How do we do number formatting for location of percentage sign (%) in angular?
  For currency, angular has i18n that supports internationalization based on the currency symbol. How about %?
  For example, in Turkish, % is put on left side (before the number) instead of on the right side.</p>
  
  <p>Is there a framework from angular to do this?</p>
