Does ⎕CT tolerance apply to complex numbers in nested arrays?
Goal Determine whether comparison tolerance ⎕CT applies to complex numbers nested inside arrays, and whether enclosing primitives such as match (≡) and find (⍳) propagate that tolerance to complex leaf elements. Uncertainty ⎕CT is well established for floating-point equality, with a default commonly near 1E-14 in Dyalog APL and implementation-specific elsewh
