Hello Michael !
Thank you for reply !
I'll take into account the use of possible wider float format for
intermediary values using something like your suggestion of redefinable
type like "glp_double_t" (actually in gcc 9 in linux x86 "double_t" and
"double" are equal).
But also leave the possibility of have it working (somehow) with
float32, float64, float80, float128, ... everywhere.
Again help/suggestions/comments are welcome !
Cheers !

I just got glpsol with "long double" working and add binaries for
anyone that want to test then here

As noted there it'll benefit from tuning the constants in
src/glpk_real.h
Any help/suggestion/comment is welcome !
Note that using long doubles everywhere
would slow down a memory bound computation.
Fetching more data would be required.
One might introduce glp_double_t.
C99 uses double_t for the type in which unnamed
intermediate results of double calculations are stored.
Use glp_double_t for locals that are not arrays,
especially running totals.
Do the casts to ensure that desired calculations
are actually done in glp_double_t.
