How it works
- Plugin will store your “price” as float so any time you will change desire number format there will be no reformatting problems.
 - Best column type in database for “price” related fields is decimal. As WordPress keep meta as type “text” I can only cast it to float. Keep it in mind.
 - Field validation is “live” thanks to https://github.com/teamdf/jquery-number.
 - When you use 
get_fieldfunction you will get preformatted number based on your settings.
