--- Comment #9 from b. <newbie-02 at gmx dot de> ---
gnumeric / goffice have found a solution / workaround to get correct powers=
 of
ten for integer exponents, see
https://gitlab.gnome.org/GNOME/goffice/-/issues/62 .=20=20
It works quite well and performant, for long doubles the table needs some s=
pace
( ~260kB ), the effort is justified because the results influence the scali=
ng,
and thus results, in almost all other rounding calculations.=20=20
In this respect, I would recommend implementing similar for glibc until a
better solution is found.=20=20
( having a bug with clear description and test program 'unconfirmed' after =
more
than 12 month is a questionable performance ... )
