Notes:
1. Conversion similar as implemented in the date() function.
2. Conversion similar as implemented in the str() function.
3. Even if only one numeral is provided, the user function gets a set containing one numeric element.
4. Conversion similar as implemented in the str() function.
5. The members in the set will be converted to string. Example: {1,2,true} -> {'1','2','true'}
