Detailed Description

Abstract base class defining the interface for handling and manipulating big integers.

TInteger is capable of representing both negative and positive integers with an absolute value of less than 2^32^(2^32). To create an integer look at RInteger. TInteger defines an interface for the RInteger implementation - it is not intended that TIntegers be copied or assigned from other TIntegers. On EKA1 platforms, this is possible, but it should be avoided.
