> Casting is when you change the type, but don't change the data.. Is that the case? That's not what I think of when I think of C-style casts. float val = 12.4;
int val_i = (int) val;
The representation in memory of `val` should not match that of `val_i`, right? The value is encoded differently and the quantity is not preserved through this transformation. I don't think that means that the data weren't changed.Maybe you're thinking of aliasing/type-punning? Casts in C do perform conversions as they do in C++. |
