BcMath\Number::divmod — Gets the quotient and modulus of an arbitrary precision number
Gets the quotient and remainder of dividing $this by num
.
num
scale
scale
explicitly specified for calculation results.
If null
, the scale
of the calculation result will be set automatically.
Returns an indexed array where the first element is the quotient as a new BcMath\Number object and the second element is the remainder as a new BcMath\Number object.
The quotient is always an integer value, so BcMath\Number::scale of the quotient will
always be 0
, regardless of whether explicitly specify scale
.
If scale
is explicitly specified, BcMath\Number::scale of the
remainder will be the specified value.
When the BcMath\Number::scale of the result's remainder object is automatically set,
the greater BcMath\Number::scale of the two numbers used for modulus operation is used.
That is, if the BcMath\Number::scales of two values are 2
and 5
respectively, the BcMath\Number::scale of the remainder
will be 5
.
This method throws a ValueError in the following cases:
num
is string and not a well-formed BCMath numeric stringscale
is outside the valid range
This method throws a DivisionByZeroError exception if
num
is 0
.
Example #1 BcMath\Number::divmod() example when scale
is not specified
<?php
echo '8.3 / 2.22' . PHP_EOL;
[$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, $rem);
?>
The above example will output:
8.3 / 2.22 object(BcMath\Number)#3 (2) { ["value"]=> string(1) "3" ["scale"]=> int(0) } object(BcMath\Number)#4 (2) { ["value"]=> string(4) "1.34" ["scale"]=> int(2) } 8.3 / 8.3 object(BcMath\Number)#2 (2) { ["value"]=> string(1) "1" ["scale"]=> int(0) } object(BcMath\Number)#5 (2) { ["value"]=> string(3) "0.0" ["scale"]=> int(1) } 10 / -3 object(BcMath\Number)#3 (2) { ["value"]=> string(2) "-3" ["scale"]=> int(0) } object(BcMath\Number)#1 (2) { ["value"]=> string(1) "1" ["scale"]=> int(0) }
Example #2 BcMath\Number::divmod() example of explicitly specifying scale
<?php
echo '8.3 / 2.22' . PHP_EOL;
[$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);
?>
The above example will output:
8.3 / 2.22 object(BcMath\Number)#3 (2) { ["value"]=> string(1) "3" ["scale"]=> int(0) } object(BcMath\Number)#4 (2) { ["value"]=> string(3) "1.3" ["scale"]=> int(1) } 8.3 / 8.3 object(BcMath\Number)#2 (2) { ["value"]=> string(1) "1" ["scale"]=> int(0) } object(BcMath\Number)#5 (2) { ["value"]=> string(6) "0.0000" ["scale"]=> int(4) } 10 / -3 object(BcMath\Number)#3 (2) { ["value"]=> string(2) "-3" ["scale"]=> int(0) } object(BcMath\Number)#1 (2) { ["value"]=> string(7) "1.00000" ["scale"]=> int(5) }
