Follow-up Comment #3, bug #31512 (project octave):

"FYI - another thing I noticed consistently with octave is that it can
compute the correct mod operation only with integers. For example, try

for pp=1:1e4
if mod(pp*.025,.1)==0"

I don't think this is a bug.  Neither .025 or .1 are exactly representable in
binary, so you are not computing what you think you are.
