point2d

A point in 2d space

npm install point2d --save

Example

var Point = require('point2d');
 
var point1 = new Point(1, 2);
console.log(point1.x); // 1
console.log(point1.y); // 2
 
var point2 = new Point(); // (0, 0)
 
console.log(new Point().distance(new Point())); // 5
 
console.log(new Point().manhattanDistance(new Point())); // 7
 
console.log(new Point(-3, 4).abs()); // (3, 4)
 
console.log(new Point(1, 2).equals(new Point(1, 2))); // true
 
console.log(new Point(1, 2).add(new Point(2, 3))); // (3, 5)
 
console.log(new Point(1, 2).sub(new Point(1, 1))); // (0, 1)

Methods

Point.distance(point2d)

Returns the Euclidean distance between this point and another point

Point.manhattanDistance(point2d)

Returns the Manhattan distance between this point and another point

Point.abs()

Returns a new point with coordinates in absolute value

Point.equals(point2d)

Returns true if the x and y coordinate of this point equals the x and y coordinate of the other point

Point.add(point2d)

Returns a new point with the coordinates added together

Point.sub(point2d)

Returns a new point with the coordinates of this point subtracted by the other point
