Quote rounding in buy transaction

Is there a way when you fill in a transaction of a asset with a quote of 0.04567 that it’s not becoming 0.05 I already set the Formatting in the performance to 5 decimals

Only the number of shares (0.2 in this case) and the amount (0.01) are stored.

So there is no way to safe the actual value in the 0.01 part? That’s always 2 decimals with EUR?

No, their is no way nor any need. As @chirlu mentioned, all calculations use the share and amount only. This information is never used nor stored anywhere.
