Detailed Description

This is a representation of arbitrary integers.

It is a wrapper of GMP integers. Arithmetic operations are via C++ infix operator forms (eg. a*b) . It is for ``casual'' uses such as characteristics and cardinalities and when initializing field elements. The integers are also represented as a LinBox ring for use in integer matrix computation, see PID-integer.h or see field/ntl-ZZ.h.
