#summary Manipulate mathematic calculation with a class java

= Operable =

With org.cajuscript.math.Operable you can do calculation using java class to manipulate each mathematic operation.

You need implement a java class, like: {{{ package cajuscript_test; public class Vector2D implements org.cajuscript.math.Operable { private int x, y = 0; public Vector2D(int x, int y) { this.x = x; this.y = y; } public int getX() { return x; } public void setX(int x) { this.x = x; } public int getY() { return y; } public void setY(int y) { this.y = y; } public Vector2D plus(Vector2D other) { return new Vector2D(x + other.x, y + other.y); } public Vector2D subtract(Vector2D other) { return new Vector2D(x - other.x, y - other.y); } public Vector2D multiply(Vector2D other) { return new Vector2D(x * other.x, y * other.y); } public Vector2D divide(Vector2D other) { return new Vector2D(x / other.x, y / other.y); } public Vector2D module(Vector2D other) { return new Vector2D(x % other.x, y % other.y); } } }}}

In CajuScript you can use the class now, like that: {{{ printVector2D action, vector # System.out.println(action + ' x = ' + vector.getX()) System.out.println(action + ' y = ' + vector.getY())

a = cajuscript_test.Vector2D(1, 2) b = cajuscript_test.Vector2D(2, 3) c = a + b printVector2D('plus', c) c = a - b printVector2D('subtract', c) c = a * b printVector2D('multiply', c) c = a / b printVector2D('divide', c) c = a % b printVector2D('module', c) }}}
