F# Operator Overloading

Operator overloading is a methodology by which you can redefine operator behavior according to your custom need. You can overload all arithmetic operators. Operators must be defined as static. All unary operators must use ~ (tiled) operator to indicate that this is unary operator.

F# Operator Overloading Example

  type OperatorOverloading(x: int, y : int) =     member this.X = x     member this.Y = y     static member (+) (v : OperatorOverloading, a) =       OperatorOverloading(a + v.X, a + v.Y)         override this.ToString() =       this.X.ToString() + ” ” + this.Y.ToString()    let operatorOverloading = OperatorOverloading(5, 3)    let operatorOverloading2 = operatorOverloading + 10      printfn “%s” (operatorOverloading.ToString())  printfn “%s” (operatorOverloading2.ToString())  

Output:

5 3  15 13
