F# Binary Arithmetic operators

Symbol	Description
+(addition, plus)	It adds two values
-(subtract, minus)	It subtracts two values
*(multiplication, times)	It multiplies two values
/(division, divided by)	It is used to divide
%(modulus, mod)	It returns remainder of division operation
**(exponentiation, to the power of)	It performs exponent operation

F# Arithmetic Operator Example

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

Output:

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

F# Unary Arithmetic Operators

Symbol	Description
+(positive)	It applies on arithmetic expressions. It does not change sign of value
-(negative,negation)	It applies on arithmetic expressions. It changes sign of value.

F# Binary Comparison Operators

Symbol	Description
=(equality, equals)	This is not an assignment operator. It is used only for comparison. This is a generic operator.
>(greater than)	It is a generic operator
<(less then)	It is a generic operator
>=(greater than or equals)	It is a generic operator
<=(less than or equals)	It is a generic operator
<>(not equal)	It is a generic operator

F# Comparison Operator Example

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

Output:
