What do the new enum iOS9 / OSX10.11 NSNumberFormatterStyle mean?

Question

iOS and OS X NSNumberFormatterStyleenum get 4 new values ​​with the new iOS 9 and OS X 10.11 SDK! They sound cool and helpful, but Apple and even Google documentation had nothing to say about them!

What do these new values ​​do when they are passed to the formula, and how do they differ from the old values?
