BcMath\Number::divmod — Gets the quotient and modulus of an arbitrary precision number
Gets the quotient and remainder of dividing $this by num.
numscalescale explicitly specified for calculation results.
If null, the scale of the calculation result will be set automatically.
Returns an indexed array where the first element is the quotient as a new BcMath\Number object and the second element is the remainder as a new BcMath\Number object.
The quotient is always an integer value, so BcMath\Number::scale of the quotient will
always be 0, regardless of whether explicitly specify scale.
If scale is explicitly specified, BcMath\Number::scale of the
remainder will be the specified value.
When the BcMath\Number::scale of the result's remainder object is automatically set,
the greater BcMath\Number::scale of the two numbers used for modulus operation is used.
That is, if the BcMath\Number::scales of two values are 2
and 5 respectively, the BcMath\Number::scale of the remainder
will be 5.
This method throws a ValueError in the following cases:
num is string and not a well-formed BCMath numeric stringscale is outside the valid range
This method throws a DivisionByZeroError exception if
num is 0.
Exemplo #1 BcMath\Number::divmod() example when scale is not specified
<?php
echo '8.3 / 2.22' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('8')->divmod(new BcMath\Number('2.22'));
var_dump($quot, $rem);
echo PHP_EOL . '8.3 / 8.3' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('8.3')->divmod('8.3');
var_dump($quot, $rem);
echo PHP_EOL . '10 / -3' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('10')->divmod(-3);
var_dump($quot, $rem);
?>O exemplo acima produzirá:
