| Aug 30, 2019 at 2:58 | comment | added | Value Ink | @Joel I'm not sure (I assume it's fine), but if the dilemma is nagging you I think it's best if asked as a separate meta post and not as a comment in here... | |
| Aug 30, 2019 at 2:47 | comment | added | Joel | I just wonder, is it appropriate for me to post solutions after getting involved in improving the challenge? | |
| Aug 30, 2019 at 2:02 | comment | added | Value Ink | @Joel good idea. Thanks for the tip | |

You may add a note saying that the returned answer can be a float (like 5.0) or an integer.

@Jitse won't that be hard for people whose languages are strongly typed or something? Although I guess they can just do -5.0 anyways. Ok, I've changed them.

I really like this challenge. It is very easy to understand and the implementation is not as trivial as it initially seems. I do think that you should include some non-decimal test cases like @Joel suggested, such as -5 and 5.

| Aug 29, 2019 at 3:20 | comment | added | Joel | @Value Ink The outcome of the modulo operation varies in different programming languages when a negative number is involved (see the big table at the right side of the wiki page). Your solution can only give correct answers in some languages. This is actually a good task to make people aware of that. By the way, the first and third test cases yield wrong results. | |

@FryAmTheEggman brings up a good point though, what's stopping people from doing something like +sign(input%1) to trivialize the challenge? Maybe I shouldn't post this after all

| Aug 28, 2019 at 0:30 | comment | added | FryAmTheEggman | @Joel That is true, and I guess also adding a check for being an integer is probably different enough in most languages? I'll leave my comment in case another similar problem emerges but it is likely that someone will make the same mistake I do, so it may be a good idea to specifically say this won't work in the challenge. | |
| Aug 27, 2019 at 23:27 | comment | added | Joel | The test case inputs may have a better coverage for all cases: [-99.9, -5, -2.0, -1.1, 0, 0.0, 1.1, 2.0, 5, 99.9]. | |
| Aug 27, 2019 at 23:02 | comment | added | Joel | @FryAmTheEggman Actually, that solution would give incorrect answers for all integers except 0. | |
| Aug 27, 2019 at 15:03 | comment | added | FryAmTheEggman |
I'm not certain if this is a dupe, since most answers to this can be an answer from the inspiration but with +sign(input) tacked on. I think that may be competitive in too many languages.
