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.

Decimal and ["x"] amounts to which is either 0, if "d" = 0, or gets arbitrarily small, when "n" tends to infinity. According to the definition of a limit, "x" is the limit of ["x"] when "n" tends to infinity. This is written as formula_7 or which is called an infinite decimal expansion of "x". Conversely, for any integer ["x"] and any sequence of digits formula_8 the (infinite) expression is an "infinite decimal expansion" of a real number "x". This expansion is unique if neither all "d" are equal to 9 nor all "d" are equal to 0 for "n" large
