What is Math.fround, what does it do and why is it so cursed?
 
lyxal
lyxal
> The Math.fround() function returns the nearest 32-bit single precision float representation of a Number.
From MDN

@emanresuA It's short for Math.frowned and it makes you sad

2:21 AM
(Found while looking for unintended cracks to this )
@RedwolfProgrammed Agreed
 
lyxal
lyxal
Dang it you stole my joke
Very rude
 
Redwolf Programmed
Redwolf Programmed
There's all sorts of cursed Math functions
 
emanresu A
emanresu A
Math.clz32
Which Arnauld used quite nicely at one point
 
Redwolf Programmed
Redwolf Programmed
They range from the somewhat esoteric (imul, clz32) to the really cursed

I was gonna say that I suppose some would say that using fround is frowned upon but no redwolf had to go steal my joke

@lyxal It seems unlikely that redwolf came all the way to Australia just to steal your joke. If I were you, I'd check your cupboards.

@RedwolfProgrammed Did you kidnap me?

No, I left you alive as a warning to the others

expm1 is a really strange one
Same with logp1
I wonder what the intended usage is

@RedwolfProgrammed don't tell me you took Aaron
 
Redwolf Programmed

Alright then, I won't tell you
 
emanresu A
emanresu A
2:24 AM
To add or subtract one from a result? Yeah, idk
 
lyxal
lyxal
@RedwolfProgrammed I think that's for better floating point accuracy
Python has functions like that
 
Redwolf Programmed
Redwolf Programmed
Oh weird, it's actually log1p not logp1
Such consistent
@lyxal Ah, you're correct
 
lyxal
lyxal
@RedwolfProgrammed well it still managed to find its way into my esolang
 
Redwolf Programmed

Vyxal?

Yep
∆E (a: number) = (e ** a) - 1 # uses math.expm1()

Seems like it'd be pretty useless in a golfing language, even as a doubly thingy
 
lyxal
lyxal
I saw it in the math library and just added it
 
Redwolf Programmed
Redwolf Programmed
But I guess there's no shortage of doubly thingies
So not including it would be kinda pointless, unless you planned on adding a ton of doubly thingies in the future
I was smortn't when making Ash and dedicated 16 whole code points to two byte commands
And another like 48 for single byte number constants

@lyxal Wdym?

@RedwolfProgrammed I'll most likely have two or maybe four in my next golfing language

@emanresuA 4 digraph characters

Oh wait there are

That's what I was thinking of

Redwolf Programmed
I'm not a huge fan of digraphs
 
emanresu A
emanresu A
¨øÞ∆k
@RedwolfProgrammed Why?
 
lyxal
lyxal
Constants, numbers, strings, lists and miscellaneous
 
Redwolf Programmed
Redwolf Programmed
They take a lot of work to implement and design, they're rarely used (by design), so you get very little use per unit of work
 
emanresu A
emanresu A
(Not in that order)
 
Redwolf Programmed
Redwolf Programmed
2:30 AM
Plus they're a tad cheaty IMO, but not enough that I oppose them for that reason
 
emanresu A
emanresu A
@RedwolfProgrammed øm is used more than a lot of the single-byters
(In v2.6 it will be ∞)
 
Redwolf Programmed
Redwolf Programmed
(If you had more than like ten it'd be cheaty since then you most likely just have something like sledgehammer, but 1-4 is perfectly fine IMO)
 
emanresu A
emanresu A
If you count modifiers as digraphs we have a lot tho
 
Redwolf Programmed
Redwolf Programmed
@RedwolfProgrammed And most with more than 4 are still fine since they don't use all of that
 
emanresu A
emanresu A
I just realised, we're going to have to go through all the answers that use builtins deprecated in v2.6 and add notes.
I still think we should go with v2.718
 
Redwolf Programmed

2:34 AM
One of Ash's design goals was to never have to update it upon release
 
lyxal

laughs in 55 vyxal releases

@RedwolfProgrammed Idea: Fix Ash, rename it to Ember, and start using it.
 
Redwolf Programmed
Redwolf Programmed
Nah, I've got something exciting planned for my next golfing language
 
lyxal
lyxal
@emanresuA but they ain't exactly digraphs, they're operators
 
Redwolf Programmed
Redwolf Programmed
I'll be starting it in January
Since that's when I started Ash
 
lyxal
lyxal
2:37 AM
@emanresuA just move the 2.6 to vyxal.pythonanywhere.com
Ez
 
emanresu A
emanresu A
Either that or rvyxal.pythonanywhere.com
Cos v2 -> v3's going to be like v1 -> v2 - 90% of programs will not work.
 
lyxal
lyxal
I'd make a version change feature but idk if I can fit many releases into just 500mb
@emanresuA why the r?
 
emanresu A
emanresu A
golf the interpreter
@lyxal For rewrite

@emanresuA save it as byte code lol

@lyxal I'd make that v3 priority.
Since then we can build version switching into the language

2:50 AM

as compared to English spanish or french spanish

That's why I need to try to get the basics set up first, so I can see if it could be easy enough and I could have alternatives for y'all to choose from

@pxeger ok i wont click it
i want a hard cover not a pdf lol

well hard cover books generally are pretty expensive, much more so ones like AOCP because it's not mainstream pop fiction

Opinions on // for integer division in a practical language?

@RedwolfPrograms I prefer :, but that's often used for other things in languages
 
Redwolf Programs
Redwolf Programs
@cairdcoinheringaahing Only problem is there's no way to know if a {- is the start of a block comment, or the start of a { ... } with a - operator at the start
I could make it so that unary - isn't allowed to be followed by whitespace, but that feels kind of weird
Maybe I could use \{ ... \}, which isn't as attractive but also isn't ambiguous

And what about single line comments? If I put ; *} abc at the end of a line, then put {* at the beginning of it, should the *} close the block comment or not?
 
user

No, it shouldn't
You're basically nesting a comment inside, so everything inside that single line comment is treated as a separate comment to be ignored
Would probably make parsing harder though

the big advantage of nested comments is you can comment something out that has comments inside it already unproblematically

@RedwolfPrograms when you say "a small amount of parsing", do you mean basically lexing? if so, the answer is no
or at least, there should be a way of doing it that doesn't require it to lex correctly
what if I want a block comment containing a lone quotation mark? I can't do that now, because it's taken as a string
or, more practically, an English sentence containing an odd number of apostrophes, because they're wrongly taken to be single quotes

Hmm, good point. maybe there should be non-nesting, simple block comments too
