Hi developers,
Here are some efforts for easy converting CELL to FP.
Please check these sources and give me a hint 
This module simply shows raster map's values.
There are three functions and two data types.
is_null_value() can be used for CRAY instead of G_is_null_value().
value2str() is used to print values of various type of raster.
cpvalue() copies src[scol] to dest[dcol].
RASTER_PTR union may free us from complicated typecasting.
RASTER_MAP_PTR has raster map type and it's data.
Just try.
Best Regards,
Huidae Cho

It seems to work fine! But generally the functions should
follow the GIS library name convention:
G_is_null_value(), ...
Do you think your new functions could become part of the
GIS library and simplify GRASS raster programming?
If so we would have to check for conflicts with existing
G_is_null_value() code. But generally such simplification is
very welcome!
Would these function be sufficient to update r.watershed to FP?
Kind regards
Markus
