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 .  
It works quite well and performant, for long doubles the table needs some space
( ~260kB ), the effort is justified because the results influence the scaling,
and thus results, in almost all other rounding calculations.  
In this respect, I would recommend implementing similar for glibc until a
better solution is found.  
( having a bug with clear description and test program 'unconfirmed' after more
than 12 month is a questionable performance ... )
