Adding a rounded geometry to your dataset becomes a pretty simple sql (assuming your data is lat/lon - just change the SRID if it isn't):</div>

line 1 creates the new column, line 2 populates it with new points with coords set to the rounded coords of the original. You still have the original to compare. Or you can drop it, as you prefer.<br>

<div dir="ltr">Hi everyone
<div>I have a problem rounding off the QgsPointXY to say 3 decimals? How can I do that?</div>
<div>If I use the numpy.round(point,decimals) then I get an np.array back as a type and not a QgsPointXY.</div>
<div>Can someone help?<br>
Kind regards</div>
