I may be misinterpreting that, but I think that refers to the case of writing numbers using Arabic digits. "Chinese" digits are, e.g., used in the Suzhou numerals http://en.wikipedia.org/wiki/Suzhou_numerals This doesn't have a decimal point at all. Instead, the second line (below or left to the actual digits) describes the power of ten and the unit of measurement (i.e. similar to scientific notation, but with ideographs for the powers of ten). In another writing system, they use 点 (U+70B9) as the decimal separator, see http://en.wikipedia.org/wiki/Chinese_numerals#Fractional_values In the same system, the integral part uses multipliers, i.e. 12345 is [1][10000][2][1000][3][100][4][10][5]; the fractional part uses regular digits.
