@Felthry cc @CoronaCoreanici ?
@CoronaCoreanici @starkatt @Felthry Honestly, squaring to get -1 is a lot /easier/ for us, with the 2D thing and multiplying-by-i-as-rotation. :3
@CoronaCoreanici @starkatt @Felthry Wait, it does?
@CoronaCoreanici @IceWolf @starkatt also I feel like 0.9999... would still be equal to 1 even if infinitesimals exist? Because you can't write an infinitesimal out like that, 1-ε is not the same as 0.9999..., right?

@Felthry @CoronaCoreanici @starkatt Well, wouldn't 0.999999... be an infinitely small amount smaller than 1, in that case? It's like a limit.
...whoo boy, this would totally break calculus wouldn't it...
@CoronaCoreanici @IceWolf @starkatt honestly limits always have felt really kludgey to us, like they're not a very elegant way of going about this kind of stuff
which is probably part of why we prefer to think of derivatives as literal ratios of infinitesimals
