|+||Short for binary-coded decimal, a format for representing decimal numbers (integers) in which each digit is represented by four bits (nybble or nibble). See byte. For example, the number 375 would be represented as: 0011 0111 0101. One advantage of BCD over binary representations is that there is no limit to the size of a number. To add another digit, you just need to add a new 4-bit sequence. In contrast, numbers represented in binary format are generally limited to the largest number that can be represented by 8, 16, 32 or 64 bits.|
