In computing and an electronic systems, binary-coded decimal (BCD) is a class of binary encodings of decimal numbers where each digit is represented by a fixed number of bits, usually four or eight. Sometimes, special bit patterns are used for a sign or other indications (e.

<data> (BCD, packed decimal) A number representation where a
number is expressed as a sequence of decimal digits and then
each decimal digit is encoded as a four-bit binary number (a
nibble). E.g. decimal 92 would be encoded as the eight-bit
sequence 1001 0010.
In some cases, the right-most nibble contains the sign
(positive or negative).
It is easier to convert decimal numbers to and from BCD than
binary and, though BCD is often converted to binary for
arithmetic processing, it is possible to build hardware that
operates directly on BCD.

EBCDIC
Extended Binary Coded Decimal Interchange Code (EBCDIC; ) is an eight-bit character encoding used mainly on IBM mainframe and IBM midrange computer operating systems. It descended from the code used with punched cards and the corresponding six-bit binary-coded decimal code used with most of IBM's computer peripherals of the late 1950s and early 1960s. It is supported by various non-IBM platforms, such as Fujitsu-Siemens' BS2000/OSD, OS-IV, MSP, and MSP-EX, the SDS Sigma series, Unisys VS/9, Unisys MCP and ICL VME.
