The decimal equivalent for a group of 4 binary digits is determined by
multiplying the binary digit by its corresponding place value and adding
these numbers.
Binary coded octal (BCO) uses an arrangement of 8 bits (one byte) to
represent a 3-digit octal number from 000 to 377 (Figure B.5). The 8 bits
are broken down into three groups: 2 bits, 3 bits and 3 bits.
