  inline Double &operator =(const double &other) { x = other; }

you fail to return *this:

> g++-5 test.cpp -O -std=c++11 -Wall
In file included from test.cpp:3:0:
Double.h: In member function ‘Double& Double::operator=(const double&)’:
Double.h:24:63: warning: no return statement in function returning non-void
