That is incorrect.

There is nothing problematic with taking a line item, discounting it, 
multiplying out for qty and _then_ rounding, that would have absolutely no 
affect on other line items, and avoids that line item having a 
rounding "error". 

Additionally, it may be arguable that each invoice line should not be rounded 
before total as well, but that's not what Robert is noting here.

(btw, the math you expressed is exactly what I had said earlier - but I am 
guessing you were replying to Robert more so than my post).
