Vector2d
Vector2d handles two-dimensional coordinates and vectors. Vectors are immutable, meaning this is a purely functional library.
Quick example
require 'vector2d'
vector = Vector2d(50, 70)
vector.aspect_ratio # => 0.714285714285714
vector.length # => 86.0232526704263
vector * 2 # => Vector2d(100,140)
vector + Vector2d(20, 30) # => Vector2d(70,100)
vector.fit(Vector2d(64, 64)) # => Vector2d(64,45)
Vector2d.parse([50, 70]) # => Vector2d(50,70)
Vector2d.parse("50x70") # => Vector2d(50,70)Documentation
