[Jprogramming] Tacit series

[km]

Verb  exp  below uses the series for monadic  ^  to calculate  ^ y .  Can you remind me how to do  exp  tacitly?  You may omit the  "clean"  part.  Verb  clean  replaces tiny real numbers by 0 .

   clean =: (* *!.1e_14@|)"0&.+.
   
   exp =: 3 : 0
  os =. 0
   s =. 1
   k =. 0
   t =. 1
while. s ~: os do.
  os =. s
   k =. >: k
   t =. t * y % k
   s =. s + t
end.
clean s
