Adding large Power values in Xcode

Question

I am new to Objective C and iPhone development.

I\'m working with a basic calculator. I want to add a large value in text field. How can I display large values like this

Answer 1

Use Double data type. And then convert it into string then pass that string to your textField.

For eg:-

double result;
NSString *strResult = [[NSNumber numberWithDouble:result] stringValue];

It will give you exponential string.

And instead of a UILabel use UITextField.
