An integer word is also a sixteen bit representation with the first bit as sign-bit and the remaining 15 bits representing the magnitude. Sign-bit 0 means positive integer, and sign-bit 1 means negative integer. +0 and -0 are counted as just 0. For example, +0 is 1 000 000 000 000 000 and -0 is 0 000 000 000 000 000.
