gmp_divexact — Exact division of numbers

### Description

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:
