This fails to work for expansions around $\infty$

comment Extract a part of Series
The last two do not work for example for x^(-1/2) + 2 x^-1 + 3 x^(-3/2) + 4 x^-2 + 5 x^(1/2) + x^1 + x^(3/2)

comment Extract a part of Series
This looks very simple, thanks! But it doesn't help when there also are fractionary powers of $x$ in the series... Is there a way to make it work as SeriesCoefficient?

Sure, sorry for the misunderstanding.

Thanks! And if I wanted the function, not only the coefficients?

comment Truncate a sum in a 'smart' way
If for example I have Sum[c[n] r^(1-n/2)+d[n] r^(n/2-1),{n,Infinity}] this will give zero

comment Truncate a sum in a 'smart' way
It is a little but uncomfortable because it does not seem to work on the whole series. I mean, unless I multiply filter[cond] individually in front of each term that can give problems, it does not work.

Well, this is not very practical if I have many excluded values
