[GRASS-dev] Rast3d_location2coord inconsistent behavior

Hi,

I have a question about Rast3d_location2coord [1]. It is casting the col,
row, depth values to integer like this:

(int) col

instead of using

(int)floor(col)

as a result, col = 0.1 => col = 0 and col = -0.1 => col = 0, which doesn't
seem correct to me. Any opinions?

Thanks, Anna

BTW, similar function Rast_northing_to_row from raster library returns
double.
