Resolution or Accuracy

There is a mixup of using sensor Resolution vs. Accuracy.
The AHT10 sensor reports the following:
Adafruit AHT10 test!
AHT10 Found!
------------------------------------
Sensor: AHT10_T
Type: Ambient Temp (C)
Driver Ver: 1
Unique ID: 257
Min Value: -40.00
Max Value: 85.00
Resolution: 0.30
------------------------------------
------------------------------------
Sensor: AHT10_H
Type: Relative Humidity (%)
Driver Ver: 1
Unique ID: 256
Min Value: 0.00
Max Value: 100.00
Resolution: 2.00
------------------------------------
The AHT10 temperature resolution is 0.01C but its overall accuracy is +/- 0.30 C.
The same goes for RH.
What is expected of sensor to enter as "resolution" parameter?
I gather that is not made clear, and causes this mixup.
(i'll enter also ticket in AHT1x library about this; these Adafruit libraries should agree on how to use this)
