Halfpenny (British decimal coin) of new pence) alongside the new decimal coinage. The halfpenny coin's obverse featured the profile of Queen Elizabeth II; the reverse featured an image of St Edward's Crown. It was minted in bronze (like the 1p and 2p coins). It was the smallest decimal coin in both size and value. The size was in proportion to the 1p and 2p coins. It soon became Britain's least favourite coin. The Treasury had continued to argue that the halfpenny was important in the fight against inflation (preventing prices from being rounded up). The coin was demonetised and withdrawn from circulation in December
Decimal computer also included instructions for packed decimal arithmetic as well as binary integer arithmetic, and binary floating point. It used 8-bit characters and introduced EBCDIC encoding, though ASCII was also supported. The Burroughs B2500 introduced in 1966 also used 8-bit EBCDIC or ASCII characters and could pack two decimal digits per byte, but it did not provide binary arithmetic, making it a decimal architecture. Several microprocessor families offer limited decimal support. For example, the 80x86 family of microprocessors provide instructions to convert one-byte BCD numbers (packed and unpacked) to binary format before or after arithmetic operations . These operations were not
