In [[nested array theory]], a simple scalar is an array encoding data from one of the | In [[nested array theory]], a '''simple scalar''' is an array encoding data from one of the language's fundamental data types such as a [[number]] or [[character]]. A simple scalar is defined to be a [[scalar]] whose only [[element]] is itself. All nested APLs specify that simple scalars [[float]], that is, a scalar array containing only a simple scalar is identical to that simple scalar. Because of this property, all arrays which are both [[simple]] and [[scalar]] are simple scalars. | ||
Simple scalars are the only arrays with [[depth]] 0. An array consisting only of simple scalars therefore has depth 1; such arrays are called [[simple]]. | Simple scalars are the only arrays with [[depth]] 0.
