Octet Calculation Table

The following table shows the breakdown of a binary octet from the left-most high-order bit to the right-most low-order bit. Also included is the exponential representation of each bit in the octet. This table can be used to help understand the binary-to-decimal conversion table, which immediately follows this table.

Bit in Octet	1 (high- order bit)	1	1	1	1	1	1	1 (low- order bit)
Decimal value	128	64	32	16	8	4	2	1
Expo-nential value	2^7	2^6	2^5	2^4	2^3	2^2	2^1	2^0
