When you need to compare the x and y, if x and y are the same as number, can use the x - y=x + y + 1 ~, then to judge the result of the positive and negative, can determine the size of the x and y,
But if x and y opposite sign, so that the result of the judgment will sometimes is positive or negative,
For bosses to reassure

Positive complement and itself, negative complement for the not add 1, so your formula is not all right
