- `Vector2:Abs(): Vector2`：Returns a new vector from the absolute values of the original's components.
- `Vector2:Ceil(): Vector2`：Returns a new vector from the ceiling of the original's components.
- `Vector2:Floor(): Vector2`：Returns a new vector from the floor of the original's components.
- `Vector2:Sign(): Vector2`：Returns a new vector from the sign (-1, 0, or 1) of the original's components.
- `Vector2:Angle(other: Vector2, isSigned: boolean): number`：Returns the angle in radians between the two vectors.
- `Vector2:Dot(v: Vector2): number`：Returns a scalar dot product of the two vectors.
- `Vector2:Lerp(v: Vector2, alpha: number): Vector2`：Returns a Vector2 linearly interpolated between this Vector2 and the given goal by the given alpha.
- `Vector2:Max(others...: Tuple): Vector2`：Returns a Vector2 with each component as the highest among the respective components of the provided Vector2 objects.
- `Vector2:Min(others...: Tuple): Vector2`：Returns a Vector2 with each component as the lowest among the respective components of the provided Vector2 objects.
- `Vector2:FuzzyEq(other: Vector2, epsilon: number): bool`：Returns true if the X and Y components of the other Vector2 are within epsilon units of each corresponding component of this Vector2.
