***************
Math_BigInteger
***************
Pure-PHP arbitrary precision integer arithmetic library.
Supports base-2, base-10, base-16, and base-256 numbers.
Uses the GMP or BCMath extensions, if available, and an internal implementation,
otherwise.
Installation

----
::
$ pear install Math_BigInteger

- significant speed-ups
- new functions: gcd(), extendedGCD(), isPrime(), random(), randomPrime(), bitwise_leftRotate(), bitwise_rightRotate(), setPrecision(), toHex(), toBits() and equals()
- PHP_Compat is now optional. Store it in your include path if you require PHP4 support but otherwise it is unrequired.
