It seems to me that Stroustrup didn't want the division in this expression int i = 10 / 3; to behave any differently than the division in this expression: float x = 10 / 3; Integer division should always be integer division, regardless of what's going to be done with the result. At least, that's what I think he had in mind. Naturally, he would have explained it much better than I'm doing... --- [ comp.std.c++ is moderated.
