The Gauss map [1] is the function where ⌊y⌋ is the floor of y, the greatest integer no larger than y. I’ve written about this map a couple times before. First, I wrote about how this map is measure-preserving. Second, I wrote about the image at the top of the post, based on Michael Trott’s […] The post Gauss map, Euclidean algorithm, and continued fractions first appeared on John D. Cook.
