bcmod — Get modulus of an arbitrary precision number
$dividend
, string $divisor
[, int $scale = 0
] ) : string
Get the remainder of dividing dividend by
divisor.
Unless divisor is zero, the result has the same sign
as dividend.
dividendThe dividend, as a string.
divisorThe divisor, as a string.
Returns the modulus as a string, or NULL if
divisor is 0.
| Versiune | Descriere |
|---|---|
| 7.2.0 |
dividend and divisor are no
longer truncated to integer, so now the behavior of
bcmod() follows fmod() rather than
the % operator.

| 7.2.0 |
The scale parameter was added.

Example #1 bcmod() example
<?php
bcscale(0);
echo bcmod( '5', '3'); // 2
echo bcmod( '5', '-3'); // 2
echo bcmod('-5', '3'); // -2
echo bcmod('-5', '-3'); // -2
?>
Example #2 bcmod() with decimals
<?php
bcscale(1);
echo bcmod('5.7', '1.3'); // 0.5 as of PHP 7.2.0; 0 previously
?>
