composer require saki/bcmath-number-polyfill
This library requires the BCMath extension. Also, since this is a polyfill, it does not support PHP 8.4 or higher. For PHP 8.2 and 8.3 only.
This is a polyfill for BcMath\Number class added in PHP 8.4.
It achieves the same behavior as much as possible, but does not support operator overloading.
RoundingMode Enum is also included. However, if it has already been defined, it will not be defined twice.
New functions such as bcround() are not included in this library.
You can treat it like anything added in PHP 8.4.
use BcMath\Number;
$number = new Number('1.23');
$rounded = $number->round(1, RoundingMode::AwayFromZero);
var_dump($rounded);
result:
object(BcMath\Number)#3 (2) {
["value"]=>
string(3) "1.3"
["scale"]=>
int(1)
}
