[GRASS5] No fp support in r.reclass

Does r.reclass have fp support? With me it reads fp numbers, but then rounds them to ints.
Looks like I will have to spend some more hard disk space using mapcalc :frowning:

Hi Gualter,

r.reclass is doing a reclassification of data. The resulting classes
are integer by definition as a class is generally a whole number.

Probably you have a different application in mind?

Yes. I made a relative index ranging from 0 to 1, but I have some
numbers above 1 (outliers). The idea was to reclass all the numbers
above 1 to -1, leaving the others the same. If I run d.reclass it will
reclass all my pixels to -1, 0 or 1.
I managed to do the same with r.mapcalc, but this takes much more time,
hard disk and CPU. Also, I could just multiply by 100, but then this
wouldn't be so nice to show.

Have a look at r.recode. That allows you to change
a range of data to something different.

Hope this helps,

Markus
