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.

oof
{+/÷⍨⍵} was for lenght
length*
it was for the length of the list, right?
Adám

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

<moon-child> @Adám should reject lone ⋄ now. Separating into two bots--yes, will do that in a bit
Konrad 'Unrooted' Klawikowski
Konrad 'Unrooted' Klawikowski
gives me how many elements there are = 8
Adám
Adám
moon-child: Great. Any idea why the bot sporadically ignores requests ^^^ ?
@Konrad'Unrooted'Klawikowski But +/ gives you the count.
Konrad 'Unrooted' Klawikowski
Konrad 'Unrooted' Klawikowski
the count of the elements = 8?
Adám
Adám
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.
Konrad 'Unrooted' Klawikowski
Konrad 'Unrooted' Klawikowski
so I don't need that +/ part?
ah

= is a dyadic function. That's not how dyadic functions work.
@DyalogAPL You could still try to execute it.

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

yeah

OK, so, can you write a function X DivisbleBy Y that returns 1 if X is divisible by Y, 0 otherwise?
Konrad 'Unrooted' Klawikowski
Konrad 'Unrooted' Klawikowski
23:21
⍵÷⍨=⍵?
oh man
Adám
Adám
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.
Konrad 'Unrooted' Klawikowski
Konrad 'Unrooted' Klawikowski
then it is it's divisor?
Adám
Adám
Sure, but what does that mean?
Konrad 'Unrooted' Klawikowski
Konrad 'Unrooted' Klawikowski
it can be divided by that and still be an int
Adám
Adám
Ah, that why we need a function to determine integerness. Write that!

this thing gave me the =< of an x

remember execution order
Konrad 'Unrooted' Klawikowski
Konrad 'Unrooted' Klawikowski
so I have to flip them?

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

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

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
