28/12/2021:
- Added is_valid_number, is_integer_number. (safe funcs you should be using on numerical inputs)
- table_shuffle now creates a copy of the table and works on it instead of changing the table itself. The end result is the same, but the table passed as argument remains untouched.
- Reworked get_time_format.
- Renamed IsOdd to is_odd.
Happy Holidays everyone!
