Example

using System.Numerics;

class Program
{
    static void Main(string[] args)
    {
        float pi = 3.14f;

        // Get Vector2 from float by requesting the first component twice
        Vector2 v2 = pi.XX();
        Assert(v2.X == pi);
        Assert(v2.Y == pi);

        v2.X = 1.0f;
        v2.Y = 3.0f;

        // Get Vector4 from Vector2 by requesting components and injecting new ones
        Vector3 v4 = v2.X_Y_(2.0f, 4.0f);
        Assert(v4.X == 1.0f);
        Assert(v4.Y == 2.0f);
        Assert(v4.Z == 3.0f);
        Assert(v4.W == 4.0f);

        // Copy the W and X component over to a Vector2
        v4.WX(ref v2);
        Assert(v2.X == 4.0f);
        Assert(v2.Y == 1.0f);
    }
