Now you've lost me. The the video starts by talking about the Minsky algorithm over the integers. Where did the reals come in? Also, if you're calculating with floating point numbers, how can you be so sure that the algorithm is exactly invertible? At 01:15 AM 6/6/2017, Bill Gosper wrote:

Important:

The algorithm described in the talk and the book is over the reals, not the integers.
