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. In 1957, India shifted to the decimal system, though for a short period of time, both decimal and non-decimal coins were in circulation. 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 and ["x"] amounts to which is either 0, if "d" = 0, or gets arbitrarily small, when "n" tends to infinity. According to the definition of a limit, "x" is the limit of ["x"] when "n" tends to infinity. This is written as formula_7 or which is called an infinite decimal expansion of "x". Conversely, for any integer ["x"] and any sequence of digits formula_8 the (infinite) expression is an "infinite decimal expansion" of a real number "x". This expansion is unique if neither all "d" are equal to 9 nor all "d" are equal to 0 for "n" large
