33 -- Long_Long_Unsigned values for use in Text_IO.Modular_IO, and the Value
36 -- Preconditions in this unit are meant for analysis only, not for run-time
37 -- checking, so that the expected exceptions are raised. This is enforced by
38 -- setting the corresponding assertion policy to Ignore. Postconditions and
39 -- contract cases should not be executed at runtime as well, in order not to
40 -- slow down the execution of these functions.
