Question

I’m trying to make a UILabel count up in decimals but it’s rounding to the nearest whole. Here is the code:

int currentTime = [totalPrice.text intValue];
    int newTime = currentTime + 2.50;
    totalPrice.text = [NSString stringWithFormat:@"%d.00", newTime];

What am I doing wrong?

P.S. I couldn’t find any other articles on StackOverflow that were helpful.

int is a datatype that only stores integers (whole numbers). Use float or double for decimal numbers, or NSDecimalNumber if you need exact representations.

float currentType = [totalPrice.text floatValue];
float newTime = currentTime + 2.5;
totalPrice.text = [NSString stringWithFormat:@"%.2f", newTime];
