# gmp_div_qr

(PHP 4 >= 4.0.4, PHP 5, PHP 7, PHP 8)

gmp_div_qr — Divide numbers and get quotient and remainder

### 说明

gmp_div_qr(GMP|int|string `$num1`, GMP|int|string `$num2`, int `$rounding_mode` = `GMP_ROUND_ZERO`): array

The function divides `num1` by `num2`.

### 参数

`num1`

  The number being divided.

  GMP 对象、int 或 string，可以按照跟在 gmp_init() 中使用字符串并自动检测 base（即当 base 等于 0 时）相同的逻辑将其解释为数字。

`num2`

  The number that `num1` is being divided by.

  GMP 对象、int 或 string，可以按照跟在 gmp_init() 中使用字符串并自动检测 base（即当 base 等于 0 时）相同的逻辑将其解释为数字。

`rounding_mode`

  See the gmp_div_q() function for description of the `rounding_mode` argument.

### 返回值

Returns an array, with the first element being `[n/d]` (the integer result of the division) and the second being `(n - [n/d] * d)` (the remainder of the division).

### 示例

示例 #1 Division of GMP numbers

`<?php
$a = gmp_init("0x41682179fbf5");
$res = gmp_div_qr($a, "0xDEFE75");
printf("Result is: q - %s, r - %s",
gmp_strval($res[0]), gmp_strval($res[1]));
?>`
