Template casting operator

[Makhno]

Hello,
Why does my cast from Vector<class Float> to Vector<float> not work? It
won't compile,

template<class Float> class Vector
{
public:
Vector(Float x1,Float y1,Float z1):x(x1),y(y1) ,z(z1){}
inline Vector<float> operator() () const;

Float x,y,z;
};

template <class Float> inline Vector<float>
Vector<Float>:: operator() () const
{
return Vector<float>(( float)x,(float) y,(float)z);
}
int main()
{
Vector<double> pd(5.6,3.4,2.4) ;

Vector<float> pf=(Vector<floa t>)pd; /* compiler error here */

}

I'd ideally like to be able to cast a Vector<double> to a Vector<float>.

I spoke too soon. It's non needed here either. But it's not because of copy initialization.

why then?

See Victor's post.

But that's just one use of the implicit conversion.

How about:

Vector<double> pd;
Vector<float> pf;
// More stuff here.
pf = pd;

?

Hmm, this still seems to work, how peculiar. Vector<> doesn't have an
assignment operator.

Yes, it does. If you don't declare one yourself, the compiler will
do it for you.
