Hi, Everyone!
Going on 2.5 years using ledger and loving it. I ran into a strange problem
that I worked out, but I'm wondering why this was an issue.
I have things split into multiple files, e.g.:
journal.ledger
investments.ledger
accounts.ldg
etc...
So I run ledger with several -f options. I have a number of aliases for
different things to simplify running it from the command line.
I have a little validation script I run before committing to git. (It just
runs a dummy ledger command with my usual options and checks for an error
and reports how things turned out.) On a recent commit it was happy with a
small update where I added two entries, one of which in journal.ledger was:
2015/05/13 some place
e: misc
e: sundry ($2.539 * 1.8)
l: credit card: big bank $-30.25
But when I subsequently ran a reg report, I got this:
> 2014/12/19 investments-r-us
> a: abc: investment banana 5.7424 ba @ $24.38
> a: abc: investment bread 2.6954 br @ $22.26
> a: abc: cash $-200
Unbalanced remainder is:
$ -0.001
Amount to balance against:
$ 199.999316
Error: Transaction does not balance
You can see that entry is from last year and it's long been settled and not
causing any issues. (This entry is in investments.ledger, unsurprisingly.)
The first thing I found was that changing the sundry entry to $4.57 made
the problem go away. But I'm wondering how a rounding problem in that entry
could cause an issue with the completely unrelated investment entry. (Also
wondering why that would cause a rounding error.)
Then: why was the file was passing my validation script? I noticed that in
the val script I had a different order for two files:
$ldg_dir/investments.ledger -f $ldg_dir/journal.ledger
And in my aliases for actually running ledger commands I was specifying
journal.ledger first. So I switched them and now my "reg" command runs
successfully, even when using * 1.8 for sundry.
So what do you guys think? Is this a rounding bug in ledger? Or is there
some reason I should run my investments file first? Or is there somewhere
I'm not specifying the right format for things?
It seems like $199.999316 should match $200.
I have $ set like so:
commodity $
format $ 1,000.00
Thank you!
Scott
