To me it would be far more difficult because of higher Ada code standards. I mean that when writing approximations in Ada the natural goal would be to have the accurate result within the interval of two adjacent machine numbers and also to have generic version for all real types. This is really hard. When using binding you basically wash your hands and do not care about quality anymore. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
