Origin Ver. and Service Release (Select Help-->About Origin): 2018b
Operating System: Win 10

Hello,

I haven't been able to find this anywhere, so sorry if it is stated within Origin help files and the question is redundant.

I have a column where its values are percentages and follow a formula. I have limited the decimals to 2 but, when Origin rounds the numbers automatically, they don't sum 100%. Where/how can I specify this boundary?

Thank you.

Use round() function https://www.originlab.com/doc/LabTalk/ref/Round-func to calculate column values with the required precision. You may need to define a procedure to correct column values if the sum still differs from 100 - e.g., by proportional distribution of the difference.

I have waited for a while to see if any other replies came up.

I already used round() function, what I need help with is the actual column value correction. Is such a thing possible? Proportional distribution seems like a great idea, but I fail to know how it could be done.

Thank you.
