README

PHP 5.x-8.x polyfill for bcmath extension

Installation

With Composer:

$ composer require phpseclib/bcmath_compat

Limitations

• extension_loaded('bcmath')

  bcmath_compat cannot make this return true. The recommended remediation is to not do this.

• ini_set('bcmath.scale', ...)

  You cannot set configuration options for extensions that are not installed. If you do ini_set('bcmath.scale', 5) on a system without bcmath installed then ini_get('bcmath.scale') will return false. It's similar to what happens when you do ini_set('zzz', 5) and then ini_get('zzz'). You'll get false back.

  The recommended remediation to doing ini_set('bcmath.scale', ...) is to do bcscale(...). The recommended remediation for doing ini_get is (if you're using PHP >= 7.3.0) to do bcscale() or (if you're using PHP < 7.3.0) to do max(0, strlen(bcadd('0', '0')) - 2).

  Note that ini_get always returns a string whereas the recommended remediations return integers.
