moon-child: Also, what do you think about splitting the bot into two, one for IRC sync and one for execution, with two different SE and IRC names? I think that'd lesson confusion.

⋄ 8 {+/÷⍨⍵=⍺} 2 7 1 8 2 8 1 8 2 8

@Konrad'Unrooted'Klawikowski 10

oof

{+/÷⍨⍵} was for lenght

length*

it was for the length of the list, right?

Yes, I realise what the mistake was. So yes, go ahead and define a "CountIn" function!

⋄{+/÷⍨⍵} 8=2 7 1 8 2 8 1 8 2 8

@Konrad'Unrooted'Klawikowski 10

hmmmmm

oh wait

Why do you keep ÷⍨ at all?

for the length, I think

Why do you want the length?

wait

⋄ +/8=2 7 1 8 2 8 1 8 2 8

<moon-child> @Adám should reject lone ⋄ now. Separating into two bots--yes, will do that in a bit

gives me how many elements there are = 8

moon-child: Great. Any idea why the bot sporadically ignores requests ^^^ ?

@Konrad'Unrooted'Klawikowski But +/ gives you the count.

the count of the elements = 8?

Yes, since 8=⍵ gives a Boolean with 1s where elements are 8, and +/ sums that, it ends up counting the 1s, no? Because counting means +1 for each.

so I don't need that +/ part?

ah

wait

⋄{+/=8⍵} 2 7 1 8 2 8 1 8 2 8

= is a dyadic function. That's not how dyadic functions work.

@DyalogAPL You could still try to execute it.

⋄{+/8=⍵} 2 7 1 8 2 8 1 8 2 8

⋄{+/=8⍵} 2 7 1 8 2 8 1 8 2 8

@Moonchild Bot confused?

ah

maybe bot doesn't like me.....

hmmm, it seems to be dropping messages

I'm just not feeling well.

picks up two, and then no more

@DyalogAPL feel better soon Buddy

@Konrad'Unrooted'Klawikowski Thanks.

<33

You can use tryapl.org to execute things meanwhile.

@Adám let the bot rest, let us finish that little thing without the bot, let him rest

sure, gonna try

Also, you may want to install a full desktop interpreter at some point.

Cool, ,., interleaves two arrays of the same size

⋄{+/8=⍵} 2 7 1 8 2 8 1 8 2 8

@Konrad'Unrooted'Klawikowski 4

this should work

yeah

OK, so, can you write a function X DivisbleBy Y that returns 1 if X is divisible by Y, 0 otherwise?

⍵÷⍨=⍵?

oh man

How on, what does it mean for one number to be able to divide another number?

Actually, let's take one simpler step first. Write a function that determines if the argument is an integer.

then it is it's divisor?

Sure, but what does that mean?

it can be divided by that and still be an int

Ah, that why we need a function to determine integerness. Write that!

I assume he hasn't learnt about that primitive yet

@rak1507 What primitive?

|

@rak1507 No need, since he has ⌊

Ah

wait

oh man

this thing gave me the =< of an x

{⌊⍵ = ⍵}?

remember execution order

so I have to flip them?

{⍵ = ⌊⍵}?

not exactly sure what you mean but maybe

yes

⋄{⌊⍵ = ⍵} 1 2 3 4

@Konrad 'Unrooted' Klawikowski
┌→──────┐
│1 1 1 1│
└~──────┘

lol

Since ⍵=⍵ will always return all 1s (which are integers) this isn't right.

⋄ {⌊⍵ = ⍵} 1.5 2.5 3.5 4.5

try that one and the other one with decimal arguments

@Bubbler
┌→──────┐
│1 1 1 1│
└~──────┘

See the problem?

@Konrad'Unrooted'Klawikowski This one is right, though.

ah

⋄ {⍵ = ⌊⍵} 1 213.7

@Konrad 'Unrooted' Klawikowski
┌→──┐
│1 0│
└~──┘

I see

OK, so now that you know if something is an integer, can you write IsDivisibleBy?

⊢=⌊ aplwiki.com/wiki/Tacit_programming

Why are there two aplcart entries for + as the conjugate

⋄ 213.7 {⍵ = ⍵÷⍺} 1 213.7

@Konrad 'Unrooted' Klawikowski
┌→──┐
│0 0│
└~──┘

thonk

wait god no

@rak1507 I only see one. The other one is "mirror across x-axis" which is conceptually something different, even if computationally the same.

How are they conceptually different if they represent the same thing

⋄ 213.7 {⍵ = ÷⍺} 1 213.7

 @Konrad 'Unrooted' Klawikowski
┌→──┐
│0 0│
└~──┘

ok, I have no other idea

what do you get for these things 8 ÷ 3, 27 ÷ 9, 3 ÷ 2, 10 ÷ 5, and how do they relate to divisibility, and how can you use the IsInteger function you wrote a moment ago

⋄ 213.7 {⍵÷⍺ = ⌊⍵} 1 213.7

@Konrad'Unrooted'Klawikowski DOMAIN ERROR

thonk

yeah sorry guys 12.40am can be a bad time for me haha

no problem lol

gonna be back in the morning, I think

I really do have no idea for that rn

sorry and thanks everyone <3

Gute Nacht

Ok, fair enough, nothing to apologise for :)

OK, get some sleep. It has been grand!

<3

Don't feel bad for not getting things instantly, pretty sure you know more APL than I did haskell after a similar amount of time

Schlaf gut.

@rak1507 Good to hear that

@Adám danke vilmal
