Hi
I tirend used r.quantile on SRTM data for Poland (min value about to 0,
max value about to 2500 m a.s.l)
r.quantile input=Polska at PERMANENT quantiles=4
percentiles=0.001,0.01,0,1,0.25,0.50,0.75,0.90,0.99,0.999 bins=1000000
and I recived:
0:0.000000:0.000000
1:0.001000:0.000000
2:0.010000:0.000000
3:0.250000:0.000000
4:0.500000:1.000000
5:0.750000:2.000000
6:0.900000:3.000000
7:0.990000:3.000000
8:0.999000:3.000000
9:1.000000:3.000000
It looks like the results are divided by 1000 and rounded to the nearest
integer.
Did I something wrong?
