| -- 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. |
