Follow-up Comment #4, bug #45481 (project octave):
Alexander:
Right! When in doubt about floating point and many
other things lookup Kahan!
You may know that way back in the 1960's IBM started
shipping 360's with floating point without guard
digits. Kahan made them fix that at a very substantial
cost to IBM. It did not fix all the problems with 360 floating
point, but it helped a lot and was really the only
realistically possible improvement.
