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). |
