Coins of the pound sterling itself was unchanged by decimalisation.) The first decimal coins – the five pence (5p) and ten pence (10p) — were introduced in 1968 in the run-up to decimalisation in order to familiarise the public with the new system. These initially circulated alongside the pre-decimal coinage and had the same size and value as the existing one shilling and two shilling coins respectively. The fifty pence (50p) coin followed in 1969, replacing the old ten shilling note. The remaining decimal coins – at the time, the half penny (p), penny (1p) and two pence (2p) — were issued in 1971 at
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
