bcdivmod — Get the quotient and modulus of an arbitrary precision number
Get the quotient and remainder of dividing num1 by
num2.
num1The dividend, as a string.
num2The divisor, as a string.
scalenull, it will default to the default scale set with bcscale(),
or fallback to the value of the
bcmath.scale INI directive.
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 string.
scale is outside the valid range.
This function throws a DivisionByZeroError
exception if num2 is 0.
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
?>
