Ada clearly failed in this aspect.

No excuse for having everyone who wants to use such a facility
to have to write it.
It is, after all, avalable ina number of languages including COBOL
and PL/I.
The simplicity and usefulness of PL/I in producing
zero suppression/insertion of characters/general editing/
in a variety of forms (integer, fixed-point, floating-point) and suitable
for business and science cannot be refuted.
As I indicated earlier, just one short line will suffice! :
put edit (d) (P'999.V999');
