Description
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).
Properties
