Follow-up Comment #1:

Yes, I have noticed that too, on LMDE.

It is easy to make the test pass by putting in a tolerance, but it isn't clear
if that is the right approach.

For small real integer powers, should we use repeated multiplication instead
of exp(log(.) * .)?  For powers up to say 1000, it would only take about 10
multiplications and so may be faster as well as avoiding this sort of
round-off.
