+/**
+ * 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).
