[GRASS-dev] r.clump on floating map

[Markus Metz]

Hi Paulo,

r.clump currently converts a floating point raster to integer, this could
explain the rather large clusters consisting of raster cells that do not
have the same values.That is easy to fix, please create a corresponding
issue on github as a reminder.

Cheers,

Markus M
