In the accounts tab or anywhere else, where I can see actual ammount of an account, I have an account (1 in 16 account) with a negative zero as a total on that account. I'm not sure why this is happenning, there are no mathematical operations causing division to "invisible" decimals. So how is this possible?

Hi,

In Skrooge, we are using a database SQLITE.
In you case, SQLITE computes not exactly 0, this is why you have -0.
Here is the SQLITE documentation explaining this:
