Is there a C# generic constraint for “real number” types? [duplicate]

Answer 1

Would this not lend itself to having seperate classes implementing IPoint?

Something like:

public interface IPoint  
{
    T X { get; set; }
    T Y { get; set; }
}

public class IntegerPoint : IPoint
{

    public int X { get; set; }
    public int Y { get; set; }
}

As the calculations will have to differ in each implementation anyway right?
