In the different Stack Exchange reputation leagues, like this one below,
there are nice $\color{green}{\text{+green}}$ or $\color{red}{\text{-red}}$ or $\color{grey}{\text{grey=0}}$ numbers called "change". What is the algorithm behind those figures?
@wythagoras It is difficult to judge from the 2 questions, but if the tag was intended for Cesaro, Abel, Borel sumamtion and similar stuff (see here), then probably sequences-and-series or divergent-series could be a better choice.
This question is sort of paired with a similar post I wrote in Stack Overflow, but not a repeat because I am asking about using another mathematical method. StackOverflow

Wikipedia gives the formulas for the Ramanujan summation of a divergent series in the two cases of a function which has no divergence at $x=0$ and at $x=1$ but what to do with a function which is divergent at both points at the same time ?
es. $$f(x)=\frac {2^x}{x^2-x}$$
Is there any method to ...
