title: How to properly format currency on ios
body: <p>I'm looking for a way to format a string into currency without using the TextField hack.</p>
  
  <p>For example, i'd like to have the number "521242" converted into "5,212.42"
  Or if I have a number under 1$, I would like it to look like this: "52" -> "0.52"</p>
  
  <p>Thanks</p>
