Binary-coded decimal negative, and any other value is considered a positive sign value (the processors will normalize a positive sign to 1100 (C)). No matter how many bytes wide a word is, there are always an even number of nibbles because each byte has two of them. Therefore, a word of "n" bytes can contain up to (2"n")−1 decimal digits, which is always an odd number of digits. A decimal number with "d" digits requires ("d"+1) bytes of storage space. For example, a 4-byte (32-bit) word can hold seven decimal digits plus a sign, and can represent values ranging from ±9,999,999. Thus
