Tuples are set of 2 to 4 values of either float or double. They are implemented by the classes: PointXY, VectorXY, where X is the dimension (2 to 4) and Y is the type (d, or f):

• Vector2f
• Vector2d
• Point2f
• Point2d
• Vector3f
• Vector3d
• Point3d
• Point3f
• Vector4d
• Vector4f
• Point4d
• Point4f

• Tuple + Tuple
• Tuple += Tuple
• Tuple * Number
• Number * Tuple
• Tuple *= Number
• - Tuple
• Tuple / Number
• Tuple - Tuple
• Tuple -= Tuple

This operators work for tuples of the same dimension. E.g. Point2f and Vector2f or Point2d and Point2f.

Vector3f a = new Vector3f(0,1,2);
Vector3f b = new Vector3f(0,2,3);
 
println(a + b); //(0.0, 3.0, 5.0)
println(a + a + b); //(0.0, 4.0, 7.0)
println(a - b); //(0.0, -1.0, -1.0)
println(a - a - b); //(0.0, -2.0, -3.0)
println(a * 3); //(0.0, 3.0, 6.0)
println(a /2); //(0.0, 0.5, 1.0)
println(a /1.3); //(0.0, 0.7692308, 1.5384616)
