bcdivmod — Get the quotient and modulus of an arbitrary precision number

Description

function bcdivmod(string $num1, string $num2, ?int $scale = null): array

Get the quotient and remainder of dividing num1 by num2.

Parameters

num1: The dividend, as a string.
num2: The divisor, as a string.
scale: This parameter is used to set the number of digits after the decimal place in the result. If null, it will default to the default scale set with bcscale(), or fallback to the value of the bcmath.scale INI directive.

Return Values

Returns an indexed array where the first element is the quotient as a string and the second element is the remainder as a string.

Errors/Exceptions

This function throws a ValueError in the following cases:

num1 or num2 is not a well-formed BCMath numeric string.
scale is outside the valid range.

This function throws a DivisionByZeroError exception if num2 is 0.

Examples

Example #1 bcdivmod() example

<?php
bcscale(0);

[$quot, $rem] = bcdivmod('5',  '3');
echo $quot; // 1
echo $rem;  // 2

[$quot, $rem] = bcdivmod('5',  '-3');
echo $quot; // -1
echo $rem;  // 2

[$quot, $rem] = bcdivmod('-5',  '3');
echo $quot; // -1
echo $rem;  // -2

[$quot, $rem] = bcdivmod('-5',  '-3');
echo $quot; // 1
echo $rem;  // -2
?>

Example #2 bcdivmod() with decimals

<?php
[$quot, $rem] = bcdivmod('5.7', '1.3', 1);
echo $quot; // 4
echo $rem;  // 0.5
?>
