Over () is a dyadic operator which takes two functions and produce a function ().

Explanation

When the resulting function is used monadically, it is the same as Atop.

  (g  h) 
g (h )

When the resulting function is used dyadically, then it forms an Over expression (which is the true purpose of this operator).

 (g  h) 
(h ) g (h )

Examples

      x1 2 3
      y4 5 6
     x +(/) y ⍝ add the max of x and max of y
9
      ⍝ same as
      (/x)+⌈/y
9
