A:
How about something like:
NSString* str = @"1223.2212311";
NSString* result = [NSString stringWithFormat:@"%.2f", [str floatValue]];

A:
If the strings aren't going to be localized, you can just use -[NSString floatValue] to parse them.

Anything presented in the UI should be ready for localization. Your customers in France want to see a , symbol for the decimal. If you use NS numberFormatter you get that for free.

This is a question about *parsing* a string into a float, not displaying a float as a string.
