Bug 334564

"Prices are set as follows:
1 IDR = 0,00006212 €
1€ = 16097,87508 IDR

deposit IDR 1 returns € 16097,87"

this looks like the prices are set
1 € = 0,00006212 IDR and
1 IDR = 16097,87508 €
which is the the other way round than you wrote.

Hi Christian,
thanks for your comments. But no, the prices were definitely not set as 
you said they might. Prices are set as I had reported:

1€ = 16097,87508 IDR
1IDR = 0,00006212 €

If prices were set reversely each of my several reports with all 
currencies set to the base currency would show garbage - but they don't.
Only if I enter deposits of less than 100 IDR garbage is produced. When 
I delete those small deposits all records show again as they should.
And secondly, if prices were set reversely, why is the conversion 
starting to produce correct results when adding deposits in the 
magnitude of 100 IDR and higher? (though the precision is still behind)

I hope I did not misunderstand your comments!? If so, sorry!

Michael

How many digits do you have in the price precision setting? That's in KMyMoney Settings > General > Global

Then this may help to find the bug. As you said and as we can see, the calculations for 100 IDR and above are correct (100 IDR = 0,006212 € ≈ 0,01 €) .

But below, somehow the exchange rate is reversed:
1 IDR = 0,00006212 € ⇒  1 IDR = 16097,87508 IDR

Here is to note that using the correct exchange rate would lead to 0 € ( 10 IDR = 0,0006212 € ≈ 0,00 €).

Hi Alvaro,
the precision is set to 8 digits

Hi Alvaro, Christian,
I entered deposits in amounts from 1 IDR to 1000000 IDR and this time 
observed the results in the Exchange Rate/Price Editor.
The resulting figures are - in the mathematical sense - anything else 
than equicontinuous.

Should I furnish you the resulting table?

Please, that will provide us an additional data point to figure out what the problem is.

Alvaro,
here comes the list.

Git commit 7f61ffb728b58bbb905bba87e184e221a7d9858a by Cristian Oneț.
Committed on 18/10/2014 at 17:41.
Pushed by conet into branch 'master'.

Fix the currency conversion dialog for really big/small conversion rates.

If the to value was equal to zero when the dialog was constructed a bad
(inverse) conversion rate was applied. This code was there since version
1.5 (on CVS) of this file. I don't understand why it was added that way
but now it's fixed.

Also fixe the prices dialog to display the prices using the configured
price precision.

Now in case that the value after conversion becomes zero the transaction
can't be entered.
