How to check Haskell infix operator precedence

Question

I can see the type of an infix operator in GHCi with :t like so:

>:t (.)
(.) :: (b -> c) -> (a -> b) -> a -> c

How can i see the operator precedence in GHCi? is that possible?

Also, bonus question, is there a way to see the source of these prelude functions through ghci?

Answer 1

:i (:info).

[Prelude]
> :i (+)
class Num a where
  (+) :: a -> a -> a
  ...
        -- Defined in `GHC.Num'
infixl 6 +
