Decimal Day old coins were returned to the banks and in this way the bulk of them were quickly taken out of circulation. The new halfpenny, penny, and twopence coins were introduced on 15 February 1971. Within two weeks of Decimal Day, the old penny (1d) and old threepenny (3d) coins had left circulation, and old sixpences were becoming rare. On 31 August 1971, the 1d and 3d were officially withdrawn from circulation, ending the transition period. The government intended that in speech the new units would be called "new pence", but the public decided that it was clearer and quicker to
Decimal computer processors, and also the Intel x86 family have special instructions that support conversion to and from BCD. The Psion Organiser I handheld computer’s manufacturer-supplied software implemented its floating point operations in software using BCD entirely. All later Psion models used binary only, rather than BCD. Decimal arithmetic is now becoming more common; for instance, three decimal types with two binary encodings were added to the 2008 IEEE 754r standard, with 7-, 16-, and 34-digit decimal significands. The IBM Power6 processor and the IBM System z9 have implemented these types using the Densely Packed Decimal binary encoding, the first in hardware
