How to overload == for System.Double

Is it possible?

If I put these in a project:

                public static bool operator ==( double lhs, double rhs )
                {
                }
                public static bool operator !=( double lhs, double rhs )
                {
                }

I get a compiler error: One of the parameters of a binary operator must be the containing type

I get this since the overloads are inside a class so they need to have parameters that are of the containing class type. My problem is that I can't put the operator overloads outside a class.

The reason I'm doing this is that I want to avoid the problems associated with exact equality comparisons of floating point numbers. I plan/wish to add a Math.Abs(lhs-rhs) <= epsilon where epsilon is some suitably small value.

Any help, or at least confirmation that I can't do what I'd like to would be appreciated.
