##### A Trig-less Line of Sight Algorithm in Two Dimensions

In many examples of 2D line-of-sight algorithms, expensive operations like trigonometry are used. Additionally, some methods have intentional inaccuracies in them for the sake of simplicity. Here, we give an algorithm which does not fudge the numbers, and uses only basic arithmetic: addition, subtraction, multiplication, and division. This is not intended to replace the existing algorithms, or even be more efficient in practice.
