PHP: Arithmetic Operators

Last update on August 19 2022 21:51:14 (UTC/GMT +8 hours)

Description

There are five basic arithmetic operators.

+ (addition)
- (subtraction)
* (multiplication)
/ (division)
% (modulus)

The operators are summarized in the following table.

Operator	Name	Example	Result
+	Addition	$x + $y	Sum of $x and $y.
-	Subtraction	$x - $y	Difference of $x and $y.
*	Multiplication	$x * $y	Product of $x and $y.
/	Division	$x / $y	Quotient of $x and $y
%	Modulus	$x % $y	Remainder of $x divided by $y.

Example:

<?php
$x=100;
$y=60;
echo "The sum of x and y is : ". ($x+$y) ."<br />";
echo "The difference between x and y is : ". ($x-$y) ."<br />";
echo "Multiplication of x and y : ". ($x*$y) ."<br />";
echo "Division of x and y : ". ($x/$y) ."<br />";
echo "Modulus of x and y : " . ($x%$y) ."<br />";
?>

Output:

The sum of x and y is : 160
The difference between x and y is : 40
Multiplication of x and y : 6000
Division of x and y : 1.6666666666667
Modulus of x and y : 40

Note : In the case of division, the operator returns a float value if the two operands are not integers.
