Is There a Way (Lisp Routine) for Changing Precision Ex-post?

[one25IT]

Let’s say I received a messy drawing with strange values beginning from the 3rd decimal place. Is there a way to clean up the drawing ex post? I do not want to change only the units, but to alter effectively the values in the drawing.

 

I’ll give an example: A Line starts at point A with x,y coordinates (10.30192,4.00234) and ends at point B (20.50134,14.80193). I want this line to be drawn from A (10.30000,4.00000) to B (20.5000,14.80000). Is this possible?

 

Thanks in advance!
