Why does Math.Floor(Double) return a value of type Double?
...ow that the value will actually be within the range of int or long, so you cast it:
double d = 1000.1234d;
int x = (int) Math.Floor(d);
but the onus for that cast is on the developer, not on Math.Floor itself. It would have been unnecessarily restrictive to make it just fail with an exception for...
What are the advantages of using nullptr?
...s. Unlike C, C++ is a strongly typed language (C does not require explicit cast from void* to any type, while C++ mandates a explicit cast). This makes the definition of NULL specified by C standard useless in many C++ expressions. For example:
std::string * str = NULL; //Case 1
void (A::*p...

...d anyway (0003 is 3 after all). Probably what you want to accomplish is to cast that number to a string (varchar) and then use the above statement.
