For example, integers are stored in n bits,

The largest positive number is that the sign bit is 0, and the rest n- 1 bits are 1, that is, 2 (n- 1)- 1.

The smallest negative number is that the sign bit is 1, and the remaining n- 1 bits are all zeros. According to the rule of complement, subtract 1 and then take the reverse, and its absolute value is 1, and the rest bits are all 0, that is, 2 (n- 1).

Therefore, the absolute value of the smallest negative integer is greater than that of the largest positive integer 1.
