But I haven't seen any decent function to perform a rounding while eliminating the error between the "sum of the rounded" and the "rounded sum", e.g. like the following table

A B C
descvaluerounded
a1000.491001
b1000.491001
c1.49 1
d1.49 1
sum2003.962004

I came with (cell C2, but copied down):
{=ROUND(B2-((1/((ROUND(B2,0)-B2)/B2))/(SUM(1/((ROUND($B$2:$B$5,0)-$B$2:$B$5)/$B$2:$B$5)))*(SUM(ROUND($B$2:$B$5,0))-SUM($B$2:$B$5))),0)}

which does the trick, but is a bit awkward.

The basic idea is correcting the error on the values in a way that creates the least error on each individual value.

Any suggestions for a more esthetically acceptable solution?

"For most users, the ROUND function is pretty self explanatory."

I was for me until I read:

Now I always check the rounding assumptions of the function I'm using.
