Hi Hamish,

I looked at the code. Internally Terraflow uses the same type for  
elevation and filled-elevation streams.   The truncation to CELL  
happens only we convert from the terraflow streams  into a GRASS grid.

in main.cc

stream2_CELL(filledstr, nrows, ncols, opt->filled_grid);

should be

stream2_FCELL(filledstr, nrows, ncols, opt->filled_grid);
or more precisely, it should be templated on the elevation type.

Technically this should be corrected, and I'll look into it . Unless  
somebody else volunteers in the meantime..
