[gdal-dev] decimal truncation when gdal_translate/gdalwarp

Hi all,

I'm creating polar gnomonic DEMs using the LOLA DEMs as input files in 
gdal. My end product is an ascii file with X Y Z values. The original 
LOLA DEM is data type integer16 and I'm trying to transform it to a 
float32. I use -ot Float32 in gdal_translate and -wt Float32 in gdalwarp 
to be sure that the data type doesn't changes during the process. The 
problem is that when I open my XYZ file, the Z column has only 3 decimal 
positions. Is there anything I'm doing wrong or am I completely wrong 
trying to do this?
