Correctly-rounded, arbitrary-precision decimal arithmetic for PHP

Documentation
-------------

[](#documentation)

See [php-decimal.github.io](https://php-decimal.github.io)

Requirements
------------

[](#requirements)

- PHP >= 7.2
- [libmpdec >= 2.4](http://www.bytereef.org/mpdecimal/download.html)

### Installing libmpdec header files

[](#installing-libmpdec-header-files)

For Fedora:

```
sudo dnf install mpdecimal-devel
```

Install
-------

[](#install)

```
pecl install decimal

```

**Alpha**:

```
pecl install decimal-alpha

```

Windows users can find *.dll* files under [releases](https://github.com/php-decimal/ext-decimal/releases).

Enable
------

[](#enable)

You can do this temporarily using `php -dextension=decimal.so` or by adding `extension=decimal.so` to your INI. If you manage PHP with [phpbrew](https://github.com/phpbrew/phpbrew), you can use `phpbrew ext enable decimal`.

Tests
-----

[](#tests)

```
php run-tests.php -P -q

```

Build from source
-----------------

[](#build-from-source)

Build a debug build of `php-src` with a prefix as follows:

```
./configure --disable-all --enable-debug --prefix /path/to/custom-php/
```

Within the folder of this extension first run `phpize` and then

```
./configure --with-php-config=/path/to/custom-php/bin/php-config CFLAGS="-Wfatal-errors -Wall -Wpedantic -Wextra -Wno-unused-parameter -Werror"
```

And finally:

```
make -jN
```

Where `N` is the number of cores available for compilation
