Welcome @cjquines!

hi

Welcome to JHT! I am definitely active here. mhm

welcome

@hyper-neutrino The trick is to mess around with Jelly enough that you can find bugs/UB to show everyone whilst exclaiming loudly :P

^

speaking of weird jelly behavior, did you know that, in jelly, -0.0/2.0 is -0.0, but 2.0/-0.0 is inf?

Yeah, cause you can't div by zero. The weird one is when you try to run -0.0÷2.0

ha

Or 2.0÷-0.0

er, yes, i meant that

wait no thats not what i meant what the heck

wait that affects V doesn't it

okay yeah that is questionable

Jelly's parsing is a wonderful thing :P

> wait that affects V doesn't it

...guess not

oh wait of course because the nilad interaction only happens... sometimes

Actually, I'm not sure why nan is there :/

i don't know when

just sometimes

@cairdcoinheringaahing ...oh yeah that is a good question

Oh right, it's parsed as -0 .0 ÷ 2.0, so computes -0 ÷ .0, then unparseable nilad's 2.0

Because you might need signed zero, but only as an integer ¯\_(ツ)_/¯

ah, of course lmao

Wait, no, it's not

It's parsed as - 0 .0 ÷ 2.0. The leading - becomes the chain's argument and we evaluate 0 .0 ÷ 2.0 monadically, ignoring the argument of -1

So it computes 0 ÷ .0, slightly less crazy :P

2.0÷-0.0 is parsed as 2.0 ÷ - 0 .0, so we calculate 2.0 ÷ - (-2.0), then output it when we encounter the unparseable nilad 0. We repeat that again with .0, then output 0.0 at the end, thus outputting [-2.0][0][0.0] (brackets added for visualisation)

CMC: Without running them, what do -0.02.0 and 2.0-0.0 output?

my guess is -0.020.0 and 2.0-00.0

considering that jelly uses way too much regex
