[GRASS-dev] compare a DCELL and FCELL question

[ming han]

Hi Everyone

    I tried to compare if grids in two rasters are the same, one raster is
FCELL and another raster is DCELL. I got different result  when I int both
raster first before comparing them; and when I float() both raster first
before I comparing them

Is there any reason for this?

Thanks
Ming
