Usually, abs(R)<abs(Y) holds for any R = MOD(X,Y).
Therefore, I'd have expected this result:
> mod(5,[0,inf])
ans =
0 5
But Octave (as well as ML) delivers
octave:7> mod(5,[0,inf])
ans =
5 NaN
Has anybody a good explanation for this *strange* behaviour?
(The argument, because ML is doing it, does not qualify).
The alternative MOD and REM are included in
octave-forge/extra/NaN/
in case somebody wants to try them.
