Coins of the pound sterling exact decimal equivalent values continued in use after 1971 alongside the new coins, albeit with new names (the shilling became equivalent to the 5p coin, with the florin equating to 10p), and the others were withdrawn almost immediately. The use of florins and shillings as legal tender in this way ended in 1991 and 1993 when the 5p and 10p coins were replaced with smaller versions. Indeed, while pre-decimalisation shillings were used as 5p coins, for a while after decimalisation many people continued to call the new 5p coin a shilling, since it remained of a pound, but was now
Decimal computer extended to wider formats and hence are now slower than using 32-bit or wider BCD 'tricks' to compute in BCD (see ). The x87 FPU has instructions to convert 10-byte (18 decimal digits) packed decimal data, although it then operates on them as floating-point numbers. The Motorola 68000 provided instructions for BCD addition and subtraction; as does the 6502. In the much later 68000 family-derived processors, these instructions were removed when the Coldfire instruction set was defined, and all IBM mainframes also provide BCD integer arithmetic in hardware. The Zilog Z80, Motorola 6800 and its derivatives, together with other 8-bit
