The old halfpenny was withdrawn from circulation on 31 July 1969, and the half-crown (2s 6d) followed on 31 December to ease the transition. (The farthing had last been minted in 1956 and had ceased to be legal tender in 1960.) There was a substantial publicity campaign in the weeks before Decimalisation Day, including a song by Max Bygraves called "Decimalisation". The BBC broadcast a series of five-minute programmes, "Decimal Five", to which The Scaffold contributed some specially written tunes. ITV
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,
