Hi,
I think printf built-in command has a bug.
% printf "%u\n" 0xffffffffffffffff
zsh: number truncated after 15 digits: ffffffffffffffff
1152921504606846975
% command printf "%u\n" 0xffffffffffffffff
18446744073709551615
I expect to get 18446744073709551615 from zsh built-in.
Regards

Zsh doesn't have an internal string-to-unsigned operation, so unsigned
is limited to the range of positive signed.
You'll note that you also can't declare zsh integer-typed variables to
be unsigned.
