> This is how it works with unsigned int and without abs.

#include <stdio.h>
#include <stdlib.h>

int main()
{
        for (int i = 20; i <= 100; i+=20)
                printf("%d = %u; abs(%d) = %u\n", -i, -i, -i, abs(-i));

        return 0;
}

% clang++38 out.cpp -o out && ./out
-20 = 4294967276; abs(-20) = 20
-40 = 4294967256; abs(-40) = 40
-60 = 4294967236; abs(-60) = 60
-80 = 4294967216; abs(-80) = 80
-100 = 4294967196; abs(-100) = 100

In other words, -100 in unsigned int is 4294967196, which is bigger than 100.
