[gmx-users] pdb2gmx conversion loss of significant figures

I recently converted a PDB file to a .gro using pdb2gmx and I noticed that
the .gro truncates and rounds a digit from the atomic co-ordinates. Am I
making a mistake somewhere?
For example on atom 1, the .pdb file lists the co-ordinates:
-> 35.375 22.352 -11.970
where the .gro lists:
-> 3.538 2.235 -1.197
The command I used was 'pdb2gmx -f input.pdb -o output.gro -ff oplsaa -water
tip5p -p topol.top -i posre.itp -ignh'
I realize that the co-ordinates are converted into nm from angstroms, but
the least significant digit is lost.
Thanks in advance for your replies,
