Example 4: To calculate the square and cube of two numbers using JavaScript arithmetic operators
<HTML>
<BODY>
<SCRIPT>
var num=5;
var sq=num**2;
var cube=num**3;
document.writeln("Square of "+num+"="+sq);
document.write("<br> <br>");
document.write("Cube of "+num+"="+cube);
</SCRIPT>
</BODY>
</HTML>
Output:
Notes
The difference between ‘/’ and ‘%’ operators is that ‘/’ operator gives the quotient and ‘%’ operator gives
the remainder obtained during division.
Assignment Operators
Assignment operators are used to assign the value of the right-hand operand to the left-hand operand.
JavaScript has only one assignment operator (=). Some other assignment operators are created by combining
the assignment operator with an arithmetic operator. These operators are also called shorthand assignment
operators or compound assignment operators.
JavaScript provides the following assignment operators:
Operator Name Description Example Output
(a=3)
= Assignment It assigns the value of the right operand to the left operand. a = 3 3
+= Addition It adds right operand to the left operand and assigns the a += 3 6
assignment result to left operand. x+=3 is equivalent to x=x+3.
–= Subtraction It subtracts right operand from the left operand and assigns a – = 3 0
assignment the result to left operand. x–=3 is equivalent to x=x–3.
