Created page with "The '''inverse''' of a function is a function that undoes its effect, computing an argument that corresponds to the given result for that function. In APL it's usually written with the Power operator as <syntaxhighlight lang=apl inline>(f⍣¯1) x</syntaxhighlight>. While some functions such as Reverse have an obvious exact inverse, others might have no valid inverse or many possible choices for a given result. Treatment of these cases varies among dialects, but..."
