BcMath\Number::divmod

PHP function Edit on GitHub ✎

(PHP 8 >= 8.4.0)

Gets the quotient and modulus of an arbitrary precision number

Description

BcMath\Number::divmod(BcMath\Number|string|int $num, int|null $scale = null): array

Gets the quotient and remainder of dividing $this by num.

Return Values

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.

Examples

BcMath\Number::divmod example when scale is not specified

php

<?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);
?>

The above example will output:

output

8.3 / 2.22
object(BcMath\Number)#3 (2) {
  ["value"]=>
  string(1) "3"
  ["scale"]=>
  int(0)
}
object(BcMath\Number)#4 (2) {
  ["value"]=>
  string(4) "1.34"
  ["scale"]=>
  int(2)
}

8.3 / 8.3
object(BcMath\Number)#2 (2) {
  ["value"]=>
  string(1) "1"
  ["scale"]=>
  int(0)
}
object(BcMath\Number)#5 (2) {
  ["value"]=>
  string(3) "0.0"
  ["scale"]=>
  int(1)
}

10 / -3
object(BcMath\Number)#3 (2) {
  ["value"]=>
  string(2) "-3"
  ["scale"]=>
  int(0)
}
object(BcMath\Number)#1 (2) {
  ["value"]=>
  string(1) "1"
  ["scale"]=>
  int(0)
}

[$quot, $rem] = new BcMath\Number('8')->divmod(new BcMath\Number('2.22'), 1);
var_dump($quot, $rem);

echo PHP_EOL . '8.3 / 8.3' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('8.3')->divmod('8.3', 4);
var_dump($quot, $rem);

echo PHP_EOL . '10 / -3' . PHP_EOL;
[$quot, $rem] = new BcMath\Number('10')->divmod(-3, 5);
var_dump($quot, $rem);
?>
