Const method with new c++ return value syntax

it's a simple question but i don't find answer.

I start to work with the new c++ return value syntax. For example :

class A
{ 
    // Old syntax
    float foo();

    // New syntax 
    auto foo() ->float;
};

But i don't know how to do the same thing for const method

class A
    { 
        // Old syntax
        float foo() const;

        // New syntax 
        auto foo() ->float const;
    };

Always detecting as returning const float. If someone know how to write correctly this kind of method, thank you in advance.

auto foo() const -> float; is the syntax.

The return type is float, not const float, and the function itself is a const member.

Note that you are allowed to use one format in the declaration and the other in the definition.
