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

gmp_div_q — Divide numbers

Description

Divides num1 by num2 and returns the integer result.

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

The result rounding is defined by therounding_mode, which can have the following values:

• [GMP_ROUND_ZERO](gmp.constants.php#constant.gmp-round-zero): The result is truncated towards 0.
• [GMP_ROUND_PLUSINF](gmp.constants.php#constant.gmp-round-plusinf): The result is rounded towards +infinity.
• [GMP_ROUND_MINUSINF](gmp.constants.php#constant.gmp-round-minusinf): The result is rounded towards -infinity.

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_div_q() example

<?php $div1 = gmp_div_q("100", "5"); echo gmp_strval($div1) . "\n";$div2 = gmp_div_q("1", "3"); echo gmp_strval($div2) . "\n";$div3 = gmp_div_q("1", "3", GMP_ROUND_PLUSINF); echo gmp_strval($div3) . "\n";$div4 = gmp_div_q("-1", "4", GMP_ROUND_PLUSINF); echo gmp_strval($div4) . "\n";$div5 = gmp_div_q("-1", "4", GMP_ROUND_MINUSINF); echo gmp_strval($div5) . "\n"; ?>

The above example will output:
