/**
* Support for arbitrary precision mathematics in PHP.
*
* Zend_Crypt_Math_BigInteger is a wrapper across three PHP extensions: bcmath, gmp
* and big_int. Since each offer similar functionality, but availability of
* each differs across installations of PHP, this wrapper attempts to select
* the fastest option available and encapsulate a subset of its functionality
* which all extensions share in common.
*
* This class requires one of the three extensions to be available. BCMATH
* while the slowest, is available by default under Windows, and under Unix
* if PHP is compiled with the flag "--enable-bcmath". GMP requires the gmp
* library from http://www.swox.com/gmp/ and PHP compiled with the "--with-gmp"
* flag. BIG_INT support is available from a big_int PHP library available from
* only from PECL (a Windows port is not available).
