show is:exact

A specialised variant of showsPrec, using precedence context zero, and returning an ordinary String.
Convert a value to Text.
Convert a value to lazy Text.
Convert Showable values to Strings
Generalized version of show. Unlike show this function is polymorphic in its result type. This makes it more convenient to work with data types like Text or ByteString. However, if you pass the result of show to a function that expects polymorphic argument, this can break type inference, so use -XTypeApplications to specify the textual type explicitly.
>>> show (42 :: Int)
"42"

>>> show (42 :: Double)
"42.0"

>>> print (show @Text True)
"True"
Generalize the Show method t return any StringLike.
Generalized version of show.
Use the Show class to create a String. Note that this is not efficient, since an intermediate [Char] is going to be created before turning into a real String.
Parse the output of the show function applied to String or Text into what was used for its input.
