[GRASS-user] map algebra logical operators on DCELL rasters not admitted? maybe docs should outline it

[G. Allegri]

Doing a logical operation with a DCELL raster within an if(x,a) statement
produces an error: "Incorrect argument types to function bitand()".
This doesn't seem to be described inside the docs, is it?

When the if() function is described it only states its behaviour in case of
NULL, 0 or "otherwise" values.
It works correctly if the maps are CELL (i.e. e value not eqaul 0 is
treated correctly whatever it is) and it's quite confusing for users having
a different behaviour, and sepcifically an error, in case of floating point
rasters, don't you think?

Regards,
giovanni
