------ Solution --------------------
No difference
As an exception, you already know the num bound to the zerofill attribute.
All generated by tools have a maximum width, which is used to remind you of the maximum number of digits of the value, so that you do not know the overflow
------ Solution --------------------
This is the same as the C-style formatted string. if the limit is exceeded, it is displayed completely.
