limitations of precision in publishing a collision object to moveit

edit

I want to publish a simple box collision object to moveit,whichi will be used for path planning later. my problem is , moveit does not seem to comply with pose messages with more than 3 decimals. (pose.position.x = 0.1234 becomes pose.position.x = 0.12)

if my pose message contain values of more than 3 decimals ,moveit seem to ignore the last decimal. is moveit itself is not able to do place objects in precision of more than 2decimals? is there a method to increase the collision objects precision ?

im a beginner in this field and any help would be highly appreciated thank you
