template specialization in friend function

[John]

I have a class

class x{

public:

template<typename X>
friend X func(X a){
....
}

// I would also want to write the following

template< >
friend double func<double>(double a){
....
}
}
Can someone help on what i am doing wrong?

Thanks,

If the function definition is inside the class, why does it need to be
a friend?

Sorry should have been

class x{

public:

template<typename X>
friend X func(X a);

// I would also want to write the following
template< >
friend double func<double>(double a);
}
