gmp_div_q

Divide numbers

Description

GMP gmp_div_q(GMPintstring $num1, GMPintstring $num2, int $rounding_mode = GMP_ROUND_ZERO)

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 the rounding_mode, which can have the following values:

  • GMP_ROUND_ZERO: The result is truncated towards 0.
  • GMP_ROUND_PLUSINF: The result is rounded towards +infinity.
  • 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:

20
0
1
0
-1
