gmp_div_qr

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

gmp_div_qr — Divide numbers and get quotient and remainder

Description

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

The function divides num1 by num2.

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).

rounding_mode

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

Return Values

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).

Examples

Example #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]));
?>
