RE: integer artithmetic

[Hall, Benjamin]

Here's R14 results:

>> a = int16(0)/int16(0)
Warning: Divide by zero.

a =

      0

>> b = Inf*int16(0)

b =

      0

>> whos

What should we do for things like

  int16(0) / int16(0)

or

  Inf * int16(0)

?

If both arguments are double, these operations genrate NaNs.  What
should Octave do, given the constraint that the result should be an
int16 object (at least I believe that's the rule that we have to
follow for compatibility)?

Should the result be int16(0)?

Can someone who has Matlab R14 say what it does?

Thanks,
