...why 2's-complement won.
Maybee conversion to/from character code is easier. Notice the conversion code in the linked article.

(1) How often do you convert from machine integers to binary character representations?
(2) If you're referring to
for(j = 0; j < bitlen; j++) {
bin[j] = (i & 1) ? '1': '0';
i >>= 1;
}
E.g.
There is no signed bit, you don't have to worry about sign; everything just works like "normal" numbers because that in fact is what it is.A pity it was never used except a few times in early computing. I'm never sure why 2's-complement won.
