The standard also defines 64-bit (8-byte) numbers called hyper integers and unsigned hyper integers. Their representations are the obvious extensions of integer and unsigned integer defined above. They are represented in two's complement notation.The most and least significant bytes are 0 and 7, respectively. Their declarations: hyper identifier; unsigned hyper identifier; (MSB) (LSB) +-------+-------+-------+-------+-------+-------+-------+-------+ |byte 0 |byte 1 |byte 2 |byte 3 |byte 4 |byte 5 |byte 6 |byte 7 | +-------+-------+-------+-------+-------+-------+-------+-------+ <----------------------------64 bits----------------------------> HYPER INTEGER UNSIGNED HYPER INTEGER
