Decimal Day weights and measures.) Around the time of Decimalisation Day, "Decimal Adders" and other converters were available to help people convert between the old and new coins. 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
Decimal enough (for all "n" greater than some natural number "N"). If all "d" for "n" > "N" equal to 9 and the limit of the sequence formula_9 is the decimal fraction obtained by replacing the last digit that is not a 9, i.e.: "d", by "d" + 1, and replacing all subsequent 9s by 0s (see 0.999...). Any such decimal fraction, i.e., "d" = 0 for "n" > "N", may be converted to its equivalent infinite decimal expansion by replacing "d" by "d" − 1, and replacing all subsequent 0s by 9s (see 0.999...). In summary, every real number that
