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
