Examples

[Test]
public void DistanceTo()
{
    var zero = new Vector2D();
    var v = new Vector2D(3, 4);
    Assert.AreEqual(5, zero.DistanceTo(v));
    Assert.AreEqual(0, zero.DistanceTo(zero));
}
[Test]
public void DistanceToSquared()
{
    var zero = new Vector2D();
    var v = new Vector2D(3, 4);
    Assert.AreEqual(25, zero.DistanceToSquared(v));
    Assert.AreEqual(0, zero.DistanceToSquared(zero));
}
[Test]
public void DistanceToLine()
{
    Assert.AreEqual(1, Vector2D.UnitX.DistanceToLine(Vector2D.Zero, Vector2D.Zero));
    Assert.AreEqual(0, Vector2D.Zero.DistanceToLine(Vector2D.Zero, Vector2D.UnitX));
    Assert.AreEqual(0, Vector2D.UnitX.DistanceToLine(Vector2D.Zero, Vector2D.UnitX));
    Assert.AreEqual(0, (-Vector2D.UnitX).DistanceToLine(Vector2D.Zero, Vector2D.UnitX));
    Assert.AreEqual(1, Vector2D.UnitY.DistanceToLine(Vector2D.Zero, Vector2D.UnitX));
    Assert.AreEqual(5, (Vector2D.One * 5).DistanceToLine(Vector2D.Zero, Vector2D.UnitX));
