Try this in your python > interpreter: > > >>> bigint = 2**(2**16) > >>> print bigint In fact, python features two built-in integer types: * plain integers (int) * long integers (long) According to the python documentation on built-in numeric types <http://docs.python.org/library/stdtypes.html#numeric-types-int-float-long-complex>, python's int is implemented using long in C. This means it has at least 32 bits, but can be larger on certain systems. E.g. on a 64bit Linux, it'll be 64 bits long, as I've just verified myself: >>> import sys >>> 2 ** 63 - 1 == sys.maxint True Python's long is unlimited in size (at the cost of performance). Conveniently, python converts from int to long as needed, even if no longs are amongst the operands: >>> sys.maxint 9223372036854775807 >>> sys.maxint + 1 9223372036854775808L (The L postfix indicates a long literal.) Conversion from long to int doesn't happen implicitly, but can be done explicitly if wanted. Cheers, Boroondas
