Question

I am having an issue with using a float in a UILabel.

float doubleNum;

floatNum = 10 / 20;

cashLabel.text = [[NSString alloc] initWithFormat:@"%f", floatNum];

If I use “floatNum = 10 / 10;” it correctly returns “1.000000000”, however, if I put in “floatNum = 10 / 20” it returns “0.0000000”. I have tried about everything I know and it does not work. I know it’s a dumb mistake, but I can’t figure it out.

Happy Holidays. 🙂

Answer 1

You need to cast one of the integer’s to a float.

Try replacing the divisional line with:

float floatNum = (float) 10 / 20;

and you should get the correct answer.

Or if possible just use floats in your division:

float floatNum = 10.0f / 20.0f;

should also work
