Is this Overloading, methods with same name in different classes and different signature?

If I have the following code in Java:

class A {

    public int add(int a , int b) {
        return (a+b);
    }
}

class B extends A {
    public float add(float a , float b) {
        return (a+b);
}

In this particular case the sub-class isn't exactly overriding the base class's add function as they have different signatures and the concept of overloading occurs only if they are in the same scope. So, is the function add(float , float) in the sub-class B treated as an entirely new function and the concept of overloading and overriding is not applicable to it? And does it use 'Static binding' or 'Dynamic Binding'?
