Most programmers want the standard to be as explicit and unambiguous as possible, and personally I think C++ cannot afford to be ambiguous about this, and that C++ should adopt what Fortran and C already have, that is truncation toward zero. A compiler with hardware that has truncation other than toward zero should then mention that in their documentation. After all, when -4 / 3 == -2 (instead of -1), while 4 / 3 == 1, then obviously something strange is going on. Regards, Maarten. --- [ comp.std.c++ is moderated.
