Bracket in F# ( let passFive f = (f 5) )

Question

let passFive f = (f 5)

let passFive f = f 5

What's difference between them?

I found they are both like below:

val passFive: (int -> 'a) -> 'a

Answer 1

They are both the same and brackets ( parentheses ) here are used like anywhere else where you want to group together the operands and increase their precedence.

printfn "%A" myfunc 5

will give error.

printfn "%A" (myfunc 5)

is how it is supposed to be written.
