{{Built-in|Depth|≡}} is a [[monadic]] [[primitive function]] that returns an array's depth. In the APL [[array model]], the '''depth''' of an array is the number of levels of [[Nested array model|nesting]] or [[box]]ing it exhibits. In some languages, Depth returns a negative result to indicate that not all paths through the array have the same depth. | {{Built-in|Depth|≡}} is a [[monadic]] [[primitive function]] that returns an array's depth.
