[Octave-bug-tracker] [bug #46658] fzero with single precision args fails to terminate

[Ceral Paquet]

Follow-up Comment #5, bug #46658 (project octave):

Nice. Works for me with all combos of single and double.

I also looked at

fminsearch.m
fsolve.m
fminbnd.m
fminunc.m

There are a couple of places where class(x0) is used but when I tested them
with with similar problems there was no problem with any combination of
single/double.

fminunc.m:  macheps = eps (class (x0));
fsolve.m:  macheps = eps (class (x0));

The TolX and TolFun are hardcoded (to 1e-7).
