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

You could set up a NSNumberFormatter with NSNumberFormatterScientificStyle and call stringFromNumber... However, the issue I think is going to be with the precision you are hoping to support requires a specialized framework. There might be one based on GNU MP Bignum library out there, but I don't know it off hand.
