The floating array model is a modification to the nested array model. It defines an array whose only element is a simple scalar to be identical to the scalar itself. In implementation terms, a simple scalar will "float" to the to of a stack of rank-0 arrays. Languages which do not make this identification are called "fixed". | The floating array model is a modification to the nested array model.

An empty array may carry additional information to indicate what type its elements would be, if it had any. In a language with homogeneous arrays, this is typically just the type: character, numeric, or boxed. In a nested array language, the prototype may be quite complex, containing an entire nested structure. | |||
An array's prototype is used to determine the value of [[Fill element|fills]] when they are required by the language. | |||
