How to install bcmath module?

The bcmath extension is typically installed by default in most PHP installations. To check if it is installed, create a PHP file with the following code:

<?php
phpinfo();

Then, open the file in a web browser. Look for the bcmath section in the output. If you see it, then bcmath is installed.

If bcmath is not installed, you can install it by compiling PHP with the --enable-bcmath option.

Alternatively, if you are using a pre-compiled version of PHP, you may be able to install the extension by using a package manager like apt-get or yum. For example, on a system that uses apt-get, you can install bcmath by running the following command:

sudo apt-get install php7.4-bcmath

Be sure to replace php7.4 with the version of PHP that you are using.

Once you have installed the extension, you will need to restart your web server for the changes to take effect.
