[Axiom-developer] [Q] %pi() vs %pi difference ?

[Vladimir Bondarenko]

Hello *,

Is there a difference between  %pi and %pi()?
If yes, how to learn about it? If not, why we
have both %pi() and %pi?

-> )set mess bot on

-> %pi() :: Complex Float

 Function Selection for pi
      Arguments: ()
      Default target type: Pi

 [1]  signature:   () -> HACKPI
      implemented: slot $ from HACKPI

-> %pi :: Complex Float

 Function Selection for pi
      Arguments: ()
