Not bad. I added that operator because I wasn't sure it was possible without it. If you have indeed done it without, then great work. :)

it is only / one needs, since that one has a singularity at zero, hence it allows to construct C-like functions (resulting in 0 or 1) like x>0 and x<0, x>=0 and x<=0, and therefore also x==0. :)

Calm down there cowboy. My "stated usage" was just how I thought up this idea. This is just a fun math puzzle to occupy your time should you choose to let it.

it's just integer division
Not sure I agree (mod is the remainder from the division), but no shorthand allowed... show your work please. :)

Sure it is, since your division rounds: a % b = a - b * (a / b) e.g. 12 % 5 = 12 - 5 * (12 / 5) 2 = 12 - 5 * 2 2 = 2

absolutely, and furthermore PIEBALD will claim the use of the C/C++ pre-processor to introduce and define new operators. :)

C++ Preprocessor? That's so kitsch. Prolog operators all the way!

Man, all that money wasted on finding the Higgs Boson, when it was hiding in the divide by zero all along!

it is not only at zero, it is everywhere, we are just too blind to see it. :)

That'll teach you to look directly into a singularity. Those accretion discs will get you every time.

Actually, I would likely define it using repeated subtraction; so it should still be allowed. :-D

Huh... I've never heard of it. Turbo BASIC has it. Dartmouth BASIC doesn't seem to. BASIC-Plus doesn't. Seems to be an abomination.

She was only a particle physicist's daughter, but she had big accretion discs. :cool:

You might want to tell these guys that. ;) Also, I intuited that it was possible. If it wasn't, then a proof of why it wasn't would have been equally valid. :)
