The LengthSquared property of the Vector4 struct provides the squared length of the vector. This is a computationally cheaper alternative to calculating the actual length, as it avoids the square root operation. It is useful in scenarios where only a relative comparison of vector lengths is needed, such as in performance-critical code.
To access the squared length of a Vector4 instance, simply use the LengthSquared property. This property is read-only and returns a float representing the squared length of the vector.
Vector4 vector = new Vector4(3.0f, 4.0f, 0.0f, 0.0f); float squaredLength = vector.LengthSquared; // squaredLength will be 25.0f, as (3^2 + 4^2 + 0^2 + 0^2) = 25
