BCD(Binary Coded Decimal) The storage of numbers in which each decimal digit is converted into binary and stored in a single character or byte. For example, a 12-digit number would take 12 bytes. See binary numbers.
|BCD and Binary|
|The BCD method codes each decimal digit in binary and stores it in its own byte. The binary method converts the entire decimal number into a binary number. In the binary example above, the 1 in the left byte is the ninth bit starting from the rightmost bit in the right byte (256-128-64-32-16-8-4-2-1-0).|
|How Numbers Are Stored|
|BCD is one of four primary ways numbers are stored in the computer.|
