Why is there need to accommodate this variant as a standard, except in terms
of subroutines for accurate input and output uniquely for those users who
wish to use them? I may be missing the point, but this seems to be a simple
numerical formatting issue for a specific and limited input group. The data
standard can remain unchanged and still allow for separate "numerical
translation" subroutines without disturbing that standard.
