Average calculation with 2 digits after the decimal point.

[Bibi44]

Good morning all,
I'm stuck on a calculation. In a calculation field, I want the average, so I enabled average with rounding "1" but rounding is bad. Here is an example, I would like 1.11 and it gives me 1.10.
Thank you all for your help.

Hello
I found, it was necessary to put "2".
Good day to all
