Have you tried using -setMaximumFractionDigits from NSNumberFormatter?

So, try something like:

[formatter setMaximumFractionDigits:2];
[formatter setMinimumFractionDigits:2];

This way you deal with NSNumberFormatter only and don't need to call anything extra on NSString.

Objective-c – Make a float only show two decimal places

It is not a matter of how the number is stored, it is a matter of how you are displaying it. When converting it to a string you must round to the desired precision, which in your case is two decimal places.

E.g.:

NSString* formattedNumber = [NSString stringWithFormat:@"%.02f", myFloat];

%.02f tells the formatter that you will be formatting a float (%f) and, that should be rounded to two places, and should be padded with 0s.

E.g.:

%f = 25.000000
%.f = 25
%.02f = 25.00

Objective-c – How to convert an NSString into an NSNumber

Use an NSNumberFormatter:

NSNumberFormatter *f = [[NSNumberFormatter alloc] init];
f.numberStyle = NSNumberFormatterDecimalStyle;
NSNumber *myNumber = [f numberFromString:@"42"];

If the string is not a valid number, then myNumber will be nil. If it is a valid number, then you now have all of the NSNumber goodness to figure out what kind of number it actually is.
