The following is a table showing conversions between the decimal and pre-decimal systems. All pre-decimal coins (except for certain non-circulating coins such as crowns, sovereigns, and double florins which were explicitly excluded from demonetisation) are now no longer legal tender. Public outcry at the proposed demise of the old sixpence (6d), worth exactly p and originally slated for early withdrawal, postponed its withdrawal until June 1980. Shillings and florins, together with their same-sized 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
