Christopher Ironside coins of the British Commonwealth had their reverse designed by Christopher Ironside. These coins were struck as (Board 1): Under the provision of the Manx Decimal Currency Act of 1970, a decimal series of coins for the Isle of Man were prepared and released on 20 October 1971 (½, 1, 2, 5, 10 and 50 new pence coins). The reverse of most of these coins was designed by Christopher Ironside. This set had the same composition and size as the corresponding British coins. These coins were struck as: 1971 first decimal set (issued from 1971 to 1974): As a country
Decimal representation result follows from dividing all sides by formula_11. Some real numbers formula_13 have two infinite decimal representations. For example, the number 1 may be equally represented by 1.000... as by 0.999... (where the infinite sequences of trailing 0's or 9's, respectively, are represented by "..."). Conventionally, the decimal representation without trailing 9's is preferred. Moreover, in the "standard decimal representation" of formula_13, an infinite sequence of trailing 0's appearing after the decimal point is omitted, along with the decimal point itself, if formula_13 is an integer. Certain procedures for constructing the decimal expansion of formula_13 will avoid the problem of
