bcdivmod — Get the quotient and modulus of an arbitrary precision number
Get the quotient and remainder of dividing num1 by
num2.
num1num2scale此可选参数用于设置结果中小数点后的小数位数。也可通过使用
bcscale() 来设置全局默认的小数位数，用于所有函数。如果未设置，则默认为 0。
Returns an indexed array where the first element is the quotient as a string and the second element is the remainder as a string.
This function throws a ValueError in the following cases:
num1 or num2 is not a well-formed BCMath numeric stringscale is outside the valid range
This function throws a DivisionByZeroError exception if num2
is 0.
示例 #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 $rem; // -2
?>示例 #2 bcdivmod() with decimals
<?php
[$quot, $rem] = bcdivmod('5.7', '1.3', 1);
echo $quot; // 4
echo $rem; // 0.5
?>
