pure virtual

Called when a double value is encountered.

MinGW struggles with long doubles http://mingw.5.n7.nabble.com/Strange-behaviour-of-gcc-4-8-1-with-long-double-td32949.html To avoid this, and to keep as many significant bits as possible we keep the components of a double separate. See JsonDouble for details.
