Twenty pence (British coin) Gardner, and used from 1982 to 2008, is a crowned Tudor rose, with the numeral "20" below the rose, and above the rose. To date, three different obverses have been used. On coins minted before the 2008 redesign, the inscription is . Coins minted after the 2008 redesign also have the year of minting on the obverse. Like all the new decimal coins introduced in 1971, until 1984 the portrait of Queen Elizabeth II by Arnold Machin appeared on the obverse, in which the Queen wears the 'Girls of Great Britain and Ireland' Tiara. Between 1985 and 1997 the portrait
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
