Hi Fusi,
If you want full float precision you can use the BT, HFF or RAW formats, which support this mode. To enable float mode, go to 'file->format preferences', then 'project maps->heightfield->HFF', click on options, then set 'ByteDepth' to 4 and enable 'FloatFlag'. The process is much the same for the BT and RAW formats. The new HFZ format supports (up to) 32-bit precision too, and also includes compression by diff and gzip encoding - it's the new heightfield format for L3DT, which will become the default later in the year.
Cheers,
Aaron.
