bcdivmod — Get the quotient and modulus of an arbitrary precision number
Get the quotient and remainder of dividing num1
by
num2
.
num1
num2
scale
This optional parameter is used to set the number
of digits after the decimal place in the result. If omitted, it will default to the scale set
globally with the bcscale() function, or fallback to 0
if
this has not been set.
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
.
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
?>
