I am implementing rounding option and to do so at the correct level, I am
trying to determine the importance of the order in which balance is
calculated. I noted that ledger calculates and add to balance in order of
parsing the postings. Even if I change the order of the postings without
changing dates and any other data , the result is going to be the same,
since ledger does not round at all for precision. Here is an example in
which I have two commodities to be evaluated in terms of GBP.
D 1000.000 GBP

gives the same result
12.000 GBP Assets
-36.492 GBP C
-32.492 GBP C1
80.984 GBP P
--------------------
12.000 GBP
, now if I round to two places after decimal per posting that does not
make sense since it does not add up to the total
12.000 GBP Assets
-36.480 GBP C
-32.480 GBP C1
80.960 GBP P
--------------------
12.000 GBP
So in order to round correctly , I must add the total such that it adds up
postings of one commodity and round it and then add to the balance. So the
result rounded to two places should be
12.000 GBP Assets
-36.490 GBP C
-32.490 GBP C1
80.980 GBP P
--------------------
12.000 GBP
My purpose is to sort the postings based on order of parsing and commodity.
So that I can round the total amount calculated from postings per
commodity, to get something like 40.49 GBP (AAA) + 40.49 GBP (XXX) = 80.98
GBP
- Will changing the order of postings affect other aspects or calculations?
Any counter example?
