| Aug 23, 2016 at 11:01 | comment | added | William Roy | Thank you very much. But how you know if this one or the other one is faster? How to determine it? | |
| Aug 23, 2016 at 10:46 | comment | added | Mikael Patel | The above solution is slow. This is a fast hack to show that you do not need all the libraries mentioned in your original question. See @EdgarBonet's answer for a solution that runs much faster. It can be improved with table lookup to avoid division/modulo. That is what the Cosa version does. | |
| Aug 23, 2016 at 10:28 | comment | added | William Roy | How would I check which answer/solution gives the faster result? I always print delta-micros() but is there a better way? | |
