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

## Installation

With [Composer](https://getcomposer.org/):

```bash

$ 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.
