Question

I have read many question in stack overflow, what I want is remove 2 or more than two trailing zero behind the decimal. i.e:

12.00 ==> 12
12.30 ==> 12.30
12.35 ==> 12.35
12.345678 ==> 12.34

Answer 1

NSNumberFormatter *twoDecimalPlacesFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[twoDecimalPlacesFormatter setMaximumFractionDigits:2];
[twoDecimalPlacesFormatter setMinimumFractionDigits:0];

return [twoDecimalPlacesFormatter stringFromNumber:number];
