Section 23.7 does not specify the return type the system functions. It can only be "integer" in order to return an integer value or X. Also returning X should actually be 1'bx to be consistent with other system functions that return 1'bx.

In section 23.7

The return type is integer and the default for the optional dimension expression is 1.

If an out-of-range dimension is specified, these functions shall return ~~a logic X~~1'bx.

If the dimension is currently empty, these functions shall return ~~a logic X~~1'bx.
