Int and String F# [closed]

Question

I have a function in F#, where I take an int value and return the int as a string.

let inttostring (x:int):string = 
    ""+x

I can't get ToString to work. Any help would be appreciated.

Answer 1

Empty string "" isn't compatible with x which is of int type. You can use

let int2String x = sprintf "%i" x

or

let int2String (x: int) = string x
