I downvoted at the cost of 1 reputation, but it shows in the achievement bubble as +-1, and it's green instead of red.


As people have noticed, positive net rep gains also contain the hyphen. The displayed number is the sum of positive and negative, but the +- is always there, though possibly only if there was at least one negative value?

  • It’s not only negative rep. I saw a “+-10” for a 10 rep increase, earlier. Rep decreases are usually not notified, so it wouldn’t be red anyway. Commented Jun 20, 2019 at 18:09
  • You're right. I just got +3 in addition to the -1, and it displayed as +-2.

    To closevoters: It is still possible to reproduce this. See this picture which I took after seeing this in the close vote queue. This is neither a bug report for a deprecated feature nor a one-off error that can no longer be reproduced. Voting to leave open Commented Jun 20, 2019 at 18:42
  • Maybe this is status-bydesign?

  • @JL2210 I don't think so. Showing negative gains is a requested feature, but to have +- is certainly confusing and a bug. If you read the OP above, it displayed +-1 for a rep gain of -1, and it displayed +-2 for a rep gain of +2. So it's showing the +- for both positive and negative net gains.

  • @mbomb007 I was thinking average gain or loss of reputation, where +-x means "positive or negative x reputation".

This is building out right now.

I had to tweak the code to pass a number around instead of a string, and I mistakenly replaced rep.IsNullOrEmpty() with rep == 0 instead of rep <= 0.

    Great, many thanks! A small nitpick: you're using a hyphen (-1), instead of a minus (−1) in the bubble. "Achievements" dropdown is using the correct symbol: i.sstatic.net/bRFhh.png Commented Jun 21, 2019 at 3:44

    It is somewhat suspicious that you had to write this code in the first place. Why would you need to invent your own string-formatting function? Converting a number to a string with the appropriate sign prefix is a built-in function in nearly every programming environment. Commented Jun 21, 2019 at 4:29
  • This was just <a>+@rep</a>, which calls ToString(). We were never meant to show non-positive numbers, so the basic formatter was fine. Commented Jun 21, 2019 at 4:33
