[Octave-bug-tracker] [bug #42589] Inaccurate results with the colon operator

[Julien Bect]

Follow-up Comment #19, bug #42589 (project octave):

Rik,

I have to disagree with you : this is NOT a psychological issue, this is a
bug.

In double precision, 10, 0.1 and 1.0 are represented exactly and the result of
10 * 0.1 - 1 is 0, even in double precision arithmetic. So, I don't see why
"technically" we should be happy that the result of (9:10) * .1 - 1 is [-.1
1e-17]...

This is also a bug in the sense of Matlab-compatiblity: Matlab returns [-.1 0]
in this situation.
