F＃算术运算符示例

module Arithmetic =
    let add (a:int, b:int):int = 
        a+b
    let sub (a:int, b:int):int = 
        a-b
    let mul (a:int, b:int):int = 
        a*b
    let div (a:int, b:int):int = 
        if b<>0 then
         a/b
        else 0
    let modu (a:int, b:int):int = 
        a%b



open Arithmetic
let addition = add (10, 10)    
let subtraction = sub (50, 20)
let multiplication = mul (10, 10)
let division = div (10, 2)
let modulus = modu (10, 3)

printfn "--------------------Result------------------"
printfn "sum = %d" addition
printfn "subtraction = %d" subtraction
printfn "multiply = %d" multiplication
printfn "division = %d" division
printfn "modulus = %d" modulus

输出：

--------------------Result------------------
sum = 20
subtraction = 30
multiply = 100
division = 5
modulus = 1

F＃一元算术运算符

F＃二进制比较运算符

F＃比较运算符示例

let comparisionOperator(a:int, b:int) = 
    if(a<b) then
        printfn "A is less than B"
    if(a>b) then
        printfn "A is greater than B"
    if(a=b) then
        printfn "A is equal to B"


comparisionOperator (10, 20)    // calling of function

输出：

A is less than B
