Coins of the pound sterling of all coins except the £2. The original intention was to exclude both the £1 and £2 coins from the redesign because they were "relatively new additions" to the coinage, but it was later decided to include the £1 coin. This was the first wholesale change to British coinage since the first decimal coins were introduced in April 1968. The new coins were initially to be put into circulation in early 2008, although they did not actually start to appear until mid-2008. The major design feature was the introduction of a reverse design shared across six coins (1p, 2p, 5p,
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
