Comment (by fredrik.johansson):
Regarding the "What is going on?!" comment: transcendental functions are
not quite deterministic due to internal caches. In this case, doing
something that results in an internal recomputation of log(2) to higher
precision leads to a slightly more accurate value later on.
This is something that I could fix with a bit of effort.
In any case, output could also change slightly between versions due to
changes in algorithms. That's an inherent drawback of doing doctests this
way...
