I probably should say integers that I can modify with bitwise operators

want to do comparison after doing bitwise operations. If the sign is
changed, the comparison will not be valid, right?
That's why I want to stay within the positive range.
You just don't care about signedness:
[EMAIL PROTECTED]:~/development/testimonials$ ./un_or_signed
-1 4294967295 4294967295 -1 EQUAL
[EMAIL PROTECTED]:~/development/testimonials$ cat un_or_signed.c
#include <stdio.h>
int main(int argc, char *argv[])
{
signed i1 = -1;
unsigned i2 = -1;
printf("%d %u %u %d %s\n", i1, i2, i1, i2, i1==i2?"EQUAL":"DIFFER");
return 0;
}
