Cool. So if I'm reading it correctly, that's exactly the same order as what I defined here, using bitPattern: http://swiftlang.ng.bluemix.net/#/repl/5791db33719d5d045b4d430c. I suppose your implementation is better in the usual case where most values are in the range of -Double.infinity ... Double.infinity.
