Integer numbers are organized exactly as above, where each bit has a unique

significance equal to two raised to the power equal to the number of the bit

position.

Floating point numbers are represented according to the IEEE Standard floating

point formats described next. The formats are described in bit order from MSB to

LSB. Remember that the bytes are “out of order” as described above according

to the Intel processor number representation convention.
