Documentation

See php-decimal.github.io

Requirements

• PHP >= 7.2
• libmpdec >= 2.4

Installing libmpdec header files

For Fedora:

sudo dnf install mpdecimal-devel

Install

pecl install decimal

Alpha:

pecl install decimal-alpha

Windows users can find .dll files under releases.

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, you can use phpbrew ext enable decimal.

Tests

php run-tests.php -P -q

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
