Decimal Day remain valid back to 1971, the only circulating coins valid on Decimal Day still to be valid. In 1982, the word "new" in "new penny" or "new pence" was removed from the inscriptions on coins, to be replaced by the number of pence in the denomination (i.e. "ten pence" or "fifty pence"). This coincided with the introduction of a new 20p coin, which, from the outset, simply bore the legend "twenty pence". A £1 coin was introduced in 1983, and a £2 coin in 1997. When the old pounds, shillings, and pence system was in operation, the United Kingdom and
Decimal prolongated into an infinite expansion by adding infinitely many 0. If the rational number is not a decimal fraction, the division may continue indefinitely. However, as all successive remainder are less than the divisor, there are only a finite number of possible remainders, and after some place, the same sequence of digits must be repeated indefinitely in the quotient. That is, one has a "repeating decimal". For example, Conversely, every eventually repeating sequence of digit is the infinite decimal expansion of a rational number. This is a consequence of the fact that the recurring part of a decimal representation is,
