Part sizing not following increments as whole number but into smaller increments when snapping to other parts

i have my part CFrame at 0, 0, 0

im sizing it up, but when i do it snaps on to the spawn and the cframe is going to increments of 0.001 or 0.01. This occurs when it snaps to a part in place.

spawn location CFrame is 0, 10, 0.

it should be sizing up to spawnlocation with the part CFrame 0, 0, 0 but its not connecting as a whole number??

in other words the part should be going up to 0, 9, 0 but its doing 9.066 for some random reason.

EDIT: im buggin out
