PHP intdiv() Function
Definition and Usage
The intdiv() function returns integer quotient of two integer parameters. If x/y results in i as division and r as remainder so that
x = y*i+r
In this case, intdiv(x,y) returns i
Syntax
intdiv ( int $x , int $y ) : int
Parameters
| Sr.No | Parameter & Description |
|---|---|
| 1 | x This parameter forms numerator part of division expression |
| 2 | y This parameter forms denominator part of division expression |
Return Values
PHP intdiv() function returns integer quotient of division of x by y. The return value is positive if both parameters are positive or both parameters are negative.
PHP Version
This function is available in PHP versions 4.x, PHP 5.x as well as PHP 7.x.
Example
Following example shows that if numerator is < denominator, intdiv() function returns 0
<?php
$x=10;
$y=3;
$r=intdiv($x, $y);
echo "intdiv(" . $x . "," . $y . ") = " . $r . "
";
$r=intdiv($y, $x);
echo "intdiv(" . $y . "," . $x . ") = " . $r;
?>Output
This will produce following result −
intdiv(10,3) = 3 intdiv(3,10) = 0
Example
In following example, intdiv() function returns negative integer because either numerator or denominator is negative −
<?php
$x=10;
$y=3;
$r=intdiv($x, $y);
echo "intdiv(" . $x . "," . $y . ") = " . $r . "
";
$x=10;
$y=-3;
$r=intdiv($x, $y);
echo "intdiv(" . $x . "," . $y . ") = " . $r . "
";
$x=-10;
$y=3;
$r=intdiv($x, $y);
echo "intdiv(" . $x . "," . $y . ") = " . $r . "
";
$x=-10;
$y=-3;
$r=intdiv($x, $y);
echo "intdiv(" . $x . "," . $y . ") = " . $r ;
?>Output
This will produce following result −
intdiv(10,3) = 3 intdiv(10,-3) = -3 intdiv(-10,3) = -3 intdiv(-10,-3) = 3
Example
Denominator is 0 in following examplee. It results in DivisionByZeroError exception -1−
<?php
$x=10;
$y=0;
$r=intdiv($x, $y);
echo "intdiv(" . $x . "," . $y . ") = " . $r . "
";
?>Output
This will produce following result −
PHP Fatal error: Uncaught DivisionByZeroError: Division by zero
Example
Fractional part in both parametera is ignored and intdiv() function is applied only to integer parts −
<?php
$x=2.90;
$y=1.90;
$r=intdiv($x, $y);
echo "intdiv(" . $x . "," . $y . ") = " . $r . "
";
?>Output
This will produce following result −
intdiv(2.9,1.9) = 2
