Question

How can I make a double appear with only two decimal places? Current code is as follows (but of course, it’s showing a lot of decimal places):

    tipPercentDbl = 20;//tipPercent as Dbl
    tipDbl = (totalDbl * (tipPercentDbl/100));//tip as Dbl
    tip.text = [NSString stringWithFormat:@"%f", tipDbl];
    tipPercent.text = [NSString stringWithFormat:@"%f", tipPercentDbl];
    totalWithTipDbl = (totalDbl+tipDbl);
    totalWithTip.text = [NSString stringWithFormat:@"%f", totalWithTipDbl];

Answer 1

Change this

tipPercent.text = [NSString stringWithFormat:@"%f", tipPercentDbl];

to this

tipPercent.text = [NSString stringWithFormat:@"%.2f", tipPercentDbl];
