[Octave-bug-tracker] [bug #59719] dec2bin issues an error for non-integer inputs while Matlab does not

[Rik]

Follow-up Comment #6, bug #59719 (project octave):

This is in keeping with Matlab.  They have such a long history, and such a
strong desire to keep new versions of Matlab backward-compatible with existing
scripts, that they often choose to lock-in strange design choices.  It would
be clearer if all base conversion routines either issued an error, or all
converted non-integer portions to zero in the same way.  Instead they've got a
mix.  I think Octave should continue with just issuing an error and letting
the programmer resolve the issue.  The generated code for this, say


x = floor (x);
y = dec2bin (x);


is *guaranteed* to work on both Matlab and Octave and is thus clearer and
platform-agnostic.
