Hello Andrew,

Very clearly a bug.  Comes from a bug in the log function (well, the
more precise internal version that is used when computing powers) in
the range [1.00099009, 1.0009901) it seems, and probably some other
ranges.  I'll investigate.

Also, I'll likely answer at some point in the next couple of days to
your juxtaposition email.  Sorry for the delay.
