NSLog format arguments

Here:

Note that this is essentially an extension of the IEEE printf format specifiers, so go to the linked page for details of (say) format options.

Thanks Q

When I first looked at this, I said, oh no, the internet. How does one know how to get there? I was messing around and I found while working with Xcode 8 under the Help menu "Documentation and API Reference". From there, right at the very top is a search textedit field. Entered NSLog but there was nothing obvious until I clicked on NSLogv. There I found the connection to "String Format Specifiers"...
