German term

Summenerhaltendes Runden

German to English Bus/Financial Mathematics & Statistics
From a disclaimer to a financial report: Prozentuelle Veränderungen beziehen sich auf die ungerundeten Werte. Die absoluten Werte sind summenerhaltend gerundet.

German info:

http://de.wikipedia.org/wiki/Rundung#Summenerhaltendes_Runde...

Could this be compensated summation? The company would like an accurate term rather than just "The absolute values have been rounded off", to clarify the difference to Mathematisches Runden.

The wiki article doesn't have an answer. Suggest "total-preserving rounding"

After an hour-long discussion with a maths graduate about the English wikipedia page, we can't see that any of the English terms fit. Maybe the German-speaking world has a different approach/categorisation?

Your German Wikipedia article links to the English one, and I'm sure the answer is in there. I'm just not sure where!

rounded maintaining their sum

Disclaimer: Not my working language direction, hence low CL.

There are several methods how to round values in a way that theirs sum is identical to that of the unrounded values (although this is usually done for proportions such as percentages, rather than for absolute values).

Anyway, we don't know which one has been used here, so I suggest that you use a similarly generic wording:

"Absolute values have been rounded maintaining their sum". To be more precise, it's the sum of the unrounded values that's maintained, but that may be a case of splitting hairs.



Peer comment(s):

agree philgoddard : There may be a more commonly used term, but this will be understood.

rounded off though remaining consistent with actual total

Percentage changes do reflect the actual values. Absolute values are rounded off, though remaining consistent with the actual total.

or: while preserving the actual total
