Yes, it is used as a digit. Its main function is to format
decimal numbers using ideographs, but otherwise with the
Western radix 10 format. Traditional ideographic numeric
formatting, on the other hand, uses an accumulate numbering
scheme:

   47,280 = <4><10000><7><1000><2><100><8><10>

Rendered using the decimal radix form, in ideographs, this is:

   47,280 = <4><7><2><8><ideographic-zero>

This use is a pervasive, if secondary, format in China and Japan,
in contexts where lining up digits makes sense, but where Western
numbers are not used.
