Will my iOS app calculate figures when a comma is used instead of a decimal point?

Solution
Actually, iOS has a handy class built-in to handle the localization of numerical values. It's called NSNumberFormatter and it specifically has the -setDecimalSeparator: method.
Problem
New to iOS development and I'm just making a little wage-type calculator for a starter. I'm exploring different features, including making the app available in France and other non-English native countries. However, as my application is heavily reliant upon calculating figures which have a decimal point in them, I want to know if iOS will calculate the figure if a comma is used as a decimal point, as countries like France use this notation: Australia/United States/other countries: ``` 12.5 * 15.8 = 197.5 ``` France/other countries: ``` 12,5 * 15,8 = 197,5 ``` I am pretty much asking a) if a comma is inserted rather than a decimal point, will it still calculate on local devices, and b) if not, what code should I include in my application such that it will calculate this notation? (Note that I am not asking for a comma as a separator, but what acts as the equivalent of a decimal point.) Thank you in advance!
