Question

I’m using the following code in xCode, to work out how much to initially zoom on a UIImage in a scroll view but it keeps returning zero.

int heightRatio = self.scrollView.bounds.size.height / self.imageView.image.size.height;

The strange thing is if I do a subtraction it works, just not with division.

XCode describes both height variables as a “GLuint”, some graphics version of int I think.

I’ve NSLogged both numbers on the right, and neither are zero.

I’ve tried defining heightRatio as a GLuint as well, with no joy, and also converting to NSNumber but it’s all just getting a bit messy.

Am I missing something?

Thanks for any feedback.

You should declare heightRatio as a double (and round later if you want to have an int).
