Follow-up Comment #2, bug #53128 (project octave):

In any case, I believe the reason that Matlab (and, therefore, Octave) treats
mixed double/int operations as int is because a constant like "2" is actually
a double precision object (and it's highly unlikely that's going to change). 
So, it would be really inconvenient to not be able to write "some_int8_value *
2" and have the result be double instead of int8.

However, maybe we could have a warning for mixed double/int operations when
the value of the double is not an exact integer.  Is that what you are asking
for?  Or do you really want a warning for any mixed int/double operations?
