-- This package contains the routines for supporting the Image attribute for
-- signed integer types up to Integer, and also for conversion operations
-- required in Text_IO.Integer_IO for such types.
-- Preconditions in this unit are meant for analysis only, not for run-time
-- checking, so that the expected exceptions are raised. This is enforced by
-- setting the corresponding assertion policy to Ignore. Postconditions and
-- contract cases should not be executed at runtime as well, in order not to
-- slow down the execution of these functions.
