It’s too bad there’s no analysis here of the comparative cost (in terms of logic gates or whatever) between this system and a conventional pair-of-numbers representation, for various operations (e.g. addition, multiplication, negation, multiplicative inversion, trigonometric functions, ...).<p>My suspicion is that this kind of thing wouldn’t have enough savings to be worthwhile except for very specialized problems, but it’s hard to guess without seeing someone try. It would be a fun thing to play with for a high school student with a bit of free time.
