Class operators [RESOLVED]

[Darkwraith]

Say that we had a class, A, in which is defined as such:

class A
{
	public:
		A& operator=(const A& rhs);
		A operator+(const float &rhs) const;
}

Now this would allow us to do things such as:

A = A + 5;

How could we make it so that:

A = 5 + A;

would be valid?

class A
{

// ...
   friend A operator+(float f, const A& a);
}


A operator+(float f, const A& a)
{
   // ....
}

Thanks for all your help.
