[ros-users] probabilities of OccupancyGrid

I want to know probabilities of OccupancyGrid
In the document, OccupancyGrid.msg has int8[] data. and It has value from 0
to 100.

However, When I use slam_gmapping in gmapping with basic data
"basic_localization_stage.bag",
I just see the value -1, 0, and 100. there is no other value like 10, 50.
Is it right?
