c# - Are there any interfaces shared by value types representing numbers? -

i able create various structures variable precision. example:

public struct point<t> t : inumber {     public t x;     public t y;      public static point<t> operator +(point<t> p1, point<t> p2)     {         return new point<t>                    {                        x = p1.x+p2.x,                        y = p1.y+p2.y                    };     } } 

i know microsoft deals creating 2 structures - point (for integers) , pointf (for floating point numbers,) if needed byte-based point, or double-precision, you'll required copy lot of old code on , change value types.

there's simple reason why cannot that: operators non-virtual, i.e., compiler must know at compile time whether p1.x+p2.x integer addition or double addition.
