Oddly, the relative error is always the same:
98 z different 2.0494565872e-16 99 z different 2.0494565872e-16
Which is nearly the same as the double precision 2.2204460492503131e-16, the difference being due to the fact that the precision is defined relative to 1, and the error in the computation are in a number relatively larger (more bits set, but not yet 2).
Fernando (Ubuntu) and I (Debian) get a different result (8.47032947254e-22) than you (Fedora) do (2.0494565872e-16).
