TypeScript - Arithmetic Operators Examples
Assume the values in variables a and b are 10 and 5 respectively.
| Operator | Description | Example |
|---|---|---|
| + (Addition) | returns the sum of the operands | a + b is 15 |
| - (Subtraction) | returns the difference of the values | a - b is 5 |
| * (Multiplication) | returns the product of the values | a * b is 50 |
| / (Division) | performs a division operation and returns the quotient | a / b is 2 |
| % (Modulus) | performs a division and returns the remainder | a % b is 0 |
| ++ (Increment) | Increments the value of the variable by one | a++ is 11 |
| -- (Decrement) | Decrements the value of the variable by one | a-- is 9 |
Example
var num1:number = 10
var num2:number = 2
var res:number = 0
res = num1 + num2
console.log("Sum: "+res);
res = num1 - num2;
console.log("Difference: "+res)
res = num1*num2
console.log("Product: "+res)
res = num1/num2
console.log("Quotient: "+res)
res = num1%num2
console.log("Remainder: "+res)
num1++
console.log("Value of num1 after increment "+num1)
num2--
console.log("Value of num2 after decrement "+num2)
On compiling, it will generate following JavaScript code.
//Generated by typescript 1.8.10
var num1 = 10;
var num2 = 2;
var res = 0;
res = num1 + num2;
console.log("Sum: " + res);
res = num1 - num2;
console.log("Difference: " + res);
res = num1 * num2;
console.log("Product: " + res);
res = num1 / num2;
console.log("Quotient: " + res);
res = num1 % num2;
console.log("Remainder: " + res);
num1++;
console.log("Value of num1 after increment " + num1);
num2--;
console.log("Value of num2 after decrement " + num2);
The output of the above program is given below −
Sum: 12 Difference: 8 Product: 20 Quotient : 5 Remainder: 0 Value of num1 after increment: 11 Value of num2 after decrement: 1
