[Bug-apl] Dyalog power operator, what does it do?

[Elias Mårtenson]

Can you guys tell me if I understand what the power operator actually does? The way I see it, it calls a function for a certain number of times, or until the function returns the same thing as its input.

I made an implementation of it, to have something to experiment with. Can you guys tell me if I did it right?

Z←N (OP powerop) V;I          

→(0≠⎕NC 'N')/skip             

N←¯1                          

skip:                         

I←0                           

Z←V                           

next:                         

→(((N≥0)∧I≥N) ∨ (I>0)∧Z≡V)/end

Z←OP V←Z                      

I←I+1                         

→next                         

end:
