Decimal enough (for all "n" greater than some natural number "N"). If all "d" for "n" > "N" equal to 9 and the limit of the sequence formula_9 is the decimal fraction obtained by replacing the last digit that is not a 9, i.e.: "d", by "d" + 1, and replacing all subsequent 9s by 0s (see 0.999...). Any such decimal fraction, i.e., "d" = 0 for "n" > "N", may be converted to its equivalent infinite decimal expansion by replacing "d" by "d" − 1, and replacing all subsequent 0s by 9s (see 0.999...). In summary, every real number that
