oneofthem dixit:
>If you shouldn't use signed ints, then how do store negative numbers?
Basically, if you have something negative, you store it
either in a signed int, or in a typedef union {
mksh_ari_t i;
mksh_uari_t u;
} mksh_ari_u;
(where ari_t and uari_t are the signed and unsigned ints,
respectively), and do all arithmetics on it by using the
unsigned access, and do comparisons (other than == and !=)
and printing using the signed access.
This is legal in POSIX, and in C as long as the system uses
two’s complement. I was told that people arguing against this
have yet failed to show a workable C implementation on a system
not using two’s complement, so… fine.
