Question

I hope you can help me out with this ‘small’ problem. I want to convert a string to a double/float.

NSString *stringValue = @"1235";
priceLabel.text = [NSString stringWithFormat:@"%d",[stringValue doubleValue]/(double)100.00];

I was hoping this to set the priceLabel to 12,35 but I get some weird long string meaning nothing to me.

I have tried:

priceLabel.text = [NSString stringWithFormat:@"%d",[stringValue intValue]/(double)100.00];

priceLabel.text = [NSString stringWithFormat:@"%d",[stringValue doubleValue]/100];

but all without success.

Answer 1

You have to use %f to show float/double value.

then %.2f means 2digits after dot

NSString *stringValue = @"1235";

NSString *str = [NSString stringWithFormat:@"%.2f",[stringValue doubleValue]/(double)100.00];

NSLog(@"str : %@ \n\n",s);

priceLabel.text = str;

OUTPUT:

str : 12.35
