BcMath\Number Polyfill

Install

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.

Description

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.

How to use

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)
}
