In APL, a '''total array ordering''', or '''TAO''', is an [[ordering]] on all arrays which is used primarily by [[Grade]] and [[Interval Index]], but optionally also by the [[comparison function]]s. Traditionally ordering is defined only for [[simple]] arrays of the same [[shape]] and [[type]], so ''TAO'' refers to the extension to [[Nested array|nested]] or [[box]]ed arrays of arbitrary [[rank]], shape, and type. | In APL, a '''total array ordering''', or '''TAO''', is an [[ordering]] on all arrays which is used primarily by [[Grade]] and [[Interval Index]], but optionally also by the [[comparison function]]s.
