Strange `indexof` behavior #540

Closed langfield closed 2 months ago

langfield commented 2 months ago

In the documentation, there is the following example.

> ⊗ 2 [1_2_3 4_5_6]
[1 3]

If the index cannot be found, the ⧻ length of the searched-in array is returned.

It appears not to conform to this description of behavior. Is this something undocumented, or a bug, or am I misunderstanding something?

PieVieRo commented 2 months ago

nah its correct it's a 2-dimensional array

[1 2 3]
[4 5 6]

and the function is applied to every row of the array individually the first element is 1 because 2 is in the second position (index 1) the second element is 3 because 2 isn't found in the second row, so it returned its length (3 elements)

Ah thanks very much, apologies for polluting your issue tracker.
