Re: [AMBER] data overflow in dx output from rism3d

The bug does indeed exist for pbsa as well.
Apparently the writing statements are casting the integers as sngl()
before writing them.
I didn't think about users needing files with that many voxels since I
originally wrote this for visualization in VMD, etc... I will work on
getting it patched in the near future.
Thanks for catching the bug!
