Questions tagged [bcd]

A binary-coded decimal (BCD) is a method of representing each decimal digit of a number with a fixed number of bits.

Though binary-coded decimal is less efficient memory-wise than 2's complement there are some advantages that result in BCD still being in use today, particularly in databases and applications where monetary and similarly sensitive data types are stored and manipulated.
