Decimal Day remain unchanged. Under the new system, the pound was retained but was divided into 100 new pence, denoted by the symbol "p". New coinage was issued alongside the old coins. The 5p and 10p coins were introduced in April 1968 and were the same size, composition, and value as the shilling and two shillings coins in circulation with them. In October 1969 the 50p coin was introduced, with the 10s note withdrawn on 20 November 1970. This reduced the number of new coins that had to be introduced on Decimal Day and meant that the public was already familiar with
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
