Why is no return type specified in this function clearly returns? [duplicate]

Question

Operator overloading

I am seeing this in a piece of sample code:

operator Vector2<float>() const    {       
  return Vector2<float>(x, y);    }

My 2 questions about this:

1) The function clearly returns, but there's no return type specified?

2) It's not clear exactly what is getting overloaded here, which operator.

Answer 1

It's a conversion operator, and the return type is Vector2<float>.
