It can have more.
No. It can be just a string; an integer and a string; a double and a string; or a reference (pointer) and a string. After that there's some weird stuff that goes on with tied scalars and so on. Basically every scalar data type keeps space for a pointer to its string equivalent as well, presumably because it's a useful thing to remember once it has been evaluated once.
