    bcdivmod

    (PHP 8 >= 8.4.0)

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

    説明

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

    Get the quotient and remainder of dividing num1 by num2.

    パラメータ

    num1

    被除数を表す文字列。

    num2

    割る数を表す文字列。

    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.

    戻り値

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

    エラー / 例外

    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.

    例

    例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
    ?>

    例2 bcdivmod() with decimals

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