It occurs to me belatedly that there might be a better way to do this.Instead of flipping value from negative to
positive,with a special
case for the smallest possible integer, we could do it the other
round. And actually, I think we can rid of neg, too.
if (value < 0) *a++ = '-';
else value = -value;
start = a;
Then we could just adjust the calculation of the actual digit.
*a++ = '0' + (-remainder);
Good idea? Bad idea? Seems cleaner to me, assuming it'll actually work...
