Question

I have a simple app that I am trying to make add two NSStrings together and produce the value in a label.

NSString *one= @"0.00";
NSString *two= @"20.15";

NSString *total = [[NSString alloc]  initWithFormat:@"%d",[one integerValue] + [two integerValue]];

label.text = [NSString stringWithFormat:@"%@",total];

This works fine except I want it to take in account the numbers past the decimal. The output becomes 20 and not 20.15.

Answer 1

Use floats instead of integers

NSString *total = [[NSString alloc]  initWithFormat:@"%f",[one floatValue] + [two floatValue]];

If you want to specify 2 decimal places, replace %f with %.2f

Note, [two integerValue] evaluates to 20 in your example. You lose the decimal precision from that point on.
