how do i raise x to power of y?

Or */y#x (shorter but doesn't work for array inputs)

'rank
 3 {y+x} 4
   ^

@copy thanks

@copy can you explain how that works?

n m/y is for (github.com/JohnEarnest/ok/blob/gh-pages/docs/Manual.md#over), so y times multiply 1 with x

it only works with oK?

what about ngn/k?

Also works in ngn/k

@PyGamer0 k is not apl! that parses as 3[{y+x}[4]] (3 applied to the result from {y+x} applied to 4). in k {} is a noun. see the grammar near the end of \h in the repl.

@ngn oh

> grammar: E:E;e|e e:nve|te| t:n|v v:tA|V n:t[E]|(E)|{E}|N

^ is that what your talking about?

@PyGamer0 yes

so how to make that work?

3{x+y}5

@PyGamer0 aplers often complain about the lack of user-defined functions that can be used infix in k, but i think that (and the fact that identifiers are always nouns too) was one of the most important improvements, as it gives the k parser the ability to parse an expression without knowing what values all variables have

@PyGamer0 {x+y}[3;5]

this is called an m-expression. it was supposed to be the notation in lisp but early on f[x;y] was replaced with s-expressions: (f x y)

@ngn ah now it makes sense as to why i can define the arguments like {[x;y] x+y}

k functions can be applied to up to 8 arguments

oh there is a limit? why?

it makes it easier/simpler/more efficient to implement some things. and in reality no one ever uses 8 args or axes, so.. :)

btw, func[x] or func[x;y], func[x;y;z] is not only the notation for function application, but also for array indexing and dictionary lookup: array[i;j], dict[key]

when there's only one argument/index/key, you can also write func x, array i, dict k

or func@i, array@i, dict@k (where @ is the "apply" verb)
