What is the correct way to express a number with all its digits?

I have the following table:

On the last column, I have expressed the numbers in billions as it is mentioned at the top. However, I want the last number (Final sample size) to be expressed fully. Is there a way that I can be specific about the fact that this is the full number and not rounded up in billions?

Thank you!

• I'm probably missing something obvious, but isn't that last sum 205 million rather than billion? – S Conroy May 10 '19 at 18:12
• In addition to the comment from @SConroy, I find the number shown for the final total quite confusing: it is still in a column headed "(in billions)", which (according to your description) is not correct. If the final total is in different units from that shown at the top of the column, then the description at the left of that row should be amplified. – TrevorD May 10 '19 at 18:36
• But you still haven't addressed the issue raised by @SConroy that there is inconsistency as to whether your final total is in millions or billions! – TrevorD May 10 '19 at 18:49
• How can the grand total be 205+ million, when the first item listed in the column is 26.5 billion, & the second item in the column is 6.01 billion? – TrevorD May 10 '19 at 18:55
• I also refer you to the comments from @JasonBassford below the accepted answer - and which postdate your last reply to me - that "the table is unclear and should be reformatted. (Personally, I'd remove the final cell from the table altogether and express it separately.)" – TrevorD May 11 '19 at 11:44
