Particles position and velocity is single precision or double precision.

Hi community:

I want to ask what is the format of particles position and velocity during running, single precision or double precision. I want to update one particle's position like "-80.0 + 0.00000001 * timestep" or keep its velocity as 0.000002 \sigma/\tau(using nve and zero_force). 

I am using the double precision version of hoomd-blue 2.9.7。I found the position can not update right or the velocity can not work right. I wonder if it is the precision problem. 

My hoomd version may be old, but if it can work in new version, please let me konw.

Thank you very much.

Thanks for spamming the board with extra messages. I said EDIT for a reason.
