| Got and order (#22110759) that has a rounding error in the order list page of
Bricklink, here are some images of the details in various sources, I thought
this was solved some months ago, but might be just the fix on the XML.

It doesn't look like a rounding error to me - the sum is taken after
rounding on the order page(s), while the XML gives the sum without rounding.
I think the way the XML does it is not quite right - if you display e.g. additional
charges rounded, then those charges should be applied/summed rounded as well.

Now I think it is not rounding error exactly, just the way total is calculated,
the rounding is done good for 23,4048 to 23,40, but that is not what is used
everywhere else, the total in the other places is a sum of the already rounded
values which shows:
13,74 + 0,17 + 9,5 = 23,41...

If you just have your store only use two decimal places, you won't run into
rounding errors. Rounding takes place in different location depending on the
applications. Sometime this is before addition and sometimes after which is
likely to cause problems when multiple systems are involved.
