Binary Coded Decimal

(B-C-D)

A code scheme for numbers that allows computer manipulation to the base ten instead of the more normal base two. BCD manipulation preserves accuracy by reducing round-off errors. The BCD encoding is performed by using a four-digit binary number to encode each digit of the base ten number. Computations are then performed using the encoded digits.
