In some countries (Germany at least) storage of financial
booking information is not permitted to use floats. And you
aren't allowed to use it for calculation of taxes etc.,
instead you must use some datatype with a fixable number of
digits after the decimal point.
Thus, only our NUMERIC/DECIMAL type or int4/8 and using the
'V' (IIRC) format specifier in to_char() should be used.
