If code generation is solved probably we can have better results with the
following:
lua 5.1.4 with double -> 150KB
lua 5.1.4 with _Decimal64 -> 2.4MB *with ***bad code generation
lua 5.1.4 with _Decimal64 -> 160KB *with hopefully ***good code generation
sqlite3 with double -> 500KB
sqlite3 with _Decimal64 -> 3MB *with ***bad code generation
sqlite3 with _Decimal64 -> 530KB *with hopefully ***good code generation
The same proportion probably will apply to any other program using _Decimal*
wich will make using _Decimal* a very interesting option.
