--- Comment #1 from Domingo Alvarez <mingodad at gmail dot com> 2011-12-19 12:17:28 UTC --- 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.
