Coins of the Indian rupee rupee, 1/4 rupee, 2 anna, 1 anna, 1/2 anna & 1 pice coins, and are referred to as the anna series or pre-decimal coinage. Under the anna series, one rupee was divided into 16 annas or 64 pice, with each anna equal to 4 pice.

To distinguish between the two pice coins in circulation, the coins minted between 1957 and 1964 were printed with the legend “Naya Paisa” (“New Paisa”). The denominations in circulation were 1, 2,
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
