gmp_divexact — Exact division of numbers

Description

function gmp_divexact(GMP|int|string $num1, GMP|int|string $num2): GMP

Divides num1 by num2, using fast "exact division" algorithm. This function produces correct results only when it is known in advance that num2 divides num1.

Parameters

num1

The number being divided.

A GMP object, an int, or a string that can be interpreted as a number following the same logic as if the string was used in gmp_init() with automatic base detection (i.e. when base is equal to 0).

num2

The number that num1 is being divided by.

A GMP object, an int, or a string that can be interpreted as a number following the same logic as if the string was used in gmp_init() with automatic base detection (i.e. when base is equal to 0).

Return Values

A GMP object.

Examples

Example #1 gmp_divexact() example

<?php
$div1 = gmp_divexact("10", "2");
echo gmp_strval($div1) . "\n";

$div2 = gmp_divexact("10", "3"); // bogus result
echo gmp_strval($div2) . "\n";
?>

The above example will output:
