Follow-up Comment #18, bug #51148 (project octave):
Although in general it is not safe something like
rem = rem(find(rem~=0,1):end);
and should be replaced by (e.g.)
rem = rem(find(abs(rem)>eps/2,1):end);
now the problem is maybe in deconv (or even in filter). For instance
[div,rem]=deconv([1.92306958582241e+15,3.20449986572221e+24,1.34271290136344e+32,2.32739765751038e+38],[7.33727670161595e+27,1.05919311870816e+36,4.56169848520627e+42])
gives rem with two leading zeros, while
[div,rem]=deconv([1.92306958582241e+15,3.204499865722215e+24,1.34271290136344e+32,2.32739765751038e+38],[7.33727670161595e+27,1.05919311870816e+36,4.56169848520627e+42])
(I added a 5 as last digit of second element of first input) gives rem with
one leading zero.
