[GRASS-user] problem with r.reclass rounding up values

Hi everyone,

I'm trying to reclass a floating point raster (continuous values from
0 to 1) using a txt file with the following rules:

0 thru 0.2 = 1
0.2 thru 0.8 = 2
0.8 thru 1 = 3

But the GRASS shell replies

0.700000 rounded up to 0
0.700000 rounded up to 0
1.300000 rounded up to 1
1.300000 rounded up to 1

And the output raster has only two values, 2 and 3 (and the input has
areas below 0.2 that should have been reclassified to 1). What am I
doing wrong?

Thanks,
Márcia
