Arbitrary precision numbers can be used to perform mathematical operations without loosing the precision of the results.

PHP applications can use the bcmath extension to perform arbitrary precision operations. However, this extension is not always available in all PHP installations.

This class provides a pure PHP based solution to perform basic operations with arbitrary precision numbers. It can be used in environments where bcmath extension is not available.
