[gmx-users] More accurate potential energy in output?

Is there really no other way to get the potential energy of the system
more accurately (6 digits)
than compiling in double precision?
Gromacs is giving eight digits after an succesfull cg minimization
even when compiled with single precision.
Eight digits would be enough for me.

Compile and run in double precision.
