In what context?  Generally GRASS uses decimal degrees internally but
reports or outputs coordinates as degrees:minutes:seconds<hemisphere>.
The only way to change this behavior would be to hack the library
code. -- Specifically, src/libes/gis/wind_format.c -- No guarantee
that'd be 100% successful, but probably would alter most cases to
use decimal degrees for output.  Some modules might use the more
specific routines found in ll_format.c, but modifying those
would more likely lead to weird problems.
