And I think that's working backward from Integer.MAX_VALUE. As for its precision, its almost irrelevant since the actual size must be a power of two; and precision is only important near the boundary of a power of two. A simple and obvious explanation is better than one that is overly precise (when it matters).

@RogerRiggs
Got it. I''ve changed it and added some docs about the calculation, please have a look again. thanks.
