-% The algorithm for \PMLogZ is the reverse engineering of the one I did
-% for \PMPowTen. I had an other approach for log10 initially but it was
-% less accurate than what testings of \PMPowTen showed. The same accuracy, even
-% slightly better, was then obtain with \PMLogZ by imitating the latter
-% algorithm (the original was faster but achieved only about 6ulp max error,
-% although most of the time the result was correct up to +2 or -2,
-% the present one appears to achieve not much worse than 1ulp maximal error).
