The last bit is used to distinguish positive and negative numbers. If the last bit is NOT set, then the number is positive. Therefore, the maximal positive number is 0x7FFFFFFF = (1<<31)-1 = 2147483647 (the last bit is not set). For the negative numbers, two's complement notation is widely used. flights arvidsjaur to feldkirchen bei graz
