brief description on why mod() can repeat?

[stevemao]

Thanks for the awesome workshop! It wasn't obvious to me why mod() can repeat objects. Although I think this is probably a maths problem, for those who don't have any maths/strong CS background it might be a bit hard to understand. Google doesn't seem to have many results on the term either.

No worries! Thanks for coming. Definitely agree that an explanation would help here — will be sure to tackle if/when I revisit the content, time permitting :)

Oh! Just realised this was more likely a question than a request. Maybe this video is useful, or this article?

Oh I thought it'd be better to add a description to the task (next to mod() or something). If you don't have the time leave it to the community :)

I completed all chapters and the first mod() question was the hardest for me too. What took me so long was trying to make the function continuous. I ended up doing it slightly different from the technique exposed in the next chapter. I did abs(mod(x, 0.5) - 0.25). But I was able to solve it after a day so maybe it's fine? You can probably decide based on analytics if the question is too hard without a further clue.
