Inquiries about seat error at DXF Import?

Translated and uploaded.
Read the AutoCAD DXF (picture in mm) drawing from a Kicad mm snap to Import Graphic.
Then, place the coordinates at 0,0 in mm Snap and check the properties.
Kicad has the back seat of the coordinates.Marked as 04999999.
On AutoCad, it’s .05.
Do I need to set options during conversion?
Or is it the error of raising, throwing, or rounding up the decimal calculation during the conversion process?
