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 In October 1969 the 50p coin was introduced, with the 10s note withdrawn on 20 November 1970.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 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
