Module documentation for 1.0.0.0

There are no documented modules for this package.

This package provides the low-level implementation of the standard Integer type based on the GNU Multiple Precision Arithmetic Library (GMP).

This package provides access to the internal representation of Integer as well as primitive operations with no proper error handling, and should only be used directly with the utmost care.
