The rounding bug is still here

Question

As of right now, I have 21,650 reputation on Meta*:

enter image description here

As I understand it, this should be rounded up to 21.7k in post owner boxes. However, it's being rounded down:

Depriving me of like .2% of my hard-earned unicorn points is a travesty! Can we change this to how it used to work?

^{* oh crap what am I doing with my life?}

Right @ShadowWizard - the issue is the behavior rounding at ##,#50 numbers — Undo, Jun 1, 2015 at 19:56

OK, maybe all the issues around localized number display are actually fixed now.

MAYBE

As of the last deploy rounding at halves should again perform as expected, instead of rounding towards evens.

I don't think it's a bug. From what I can see, Stack Exchange is applying Round half to even rule:

A tie-breaking rule that is less biased is round half to even, namely:

If the fraction of y is 0.5, then q is the even integer nearest to y.

As a proof, I just found a user who currently have exactly 15150 reputation points. Lo and behold!

15150 is round to 15.2k as expected.

No, it's a bug. We used to round to away from 0, my changes switched it to round towards even. Fixing...

@Kevin haha, but you could use this as escape route, mark as status-bydesign and be on your merry way. :-D
