Intersecting shapes using Pathfinder leaves residue
In the figure on left, the black shape represents the result intersecting the yellow circle and the gray shape. If I zoom it to 64k% (figure on the right), I see a sliver of yellow between the gray and black shapes which means that the intersect tool is ls leaving a 'residue' which it ideally should not and therefore the result is not accurate. I've tried this on both Mac and Windows systems running 2017.0.2 release of Illustrator CC but the result is the same.
Can't seem to understand the reason for this 'gap' between the two paths on intersection as is clearly visible from the outline view.
