title: MVC3 Number format
body: <p>I'm developing an MVC3 application and I have the problem that many users according with their preferences prefer dot as decimal separator or comma (for example the download of Excel files using a csv file with changed extension required a specific format for avoiding user have to replace dot for comma and viceversa).
  My solution for now is a radiobutton and store everything as string and replace the default by the selected value (comma or dot)
  There is another solution which avoid the transformation of everything to string?</p>
