[GRASSLIST:1391] converting double to float

Hi,
  I would like to convert a double precision raster grid (generated by
s.surf.rst from xyz site data) to a floating point raster grid. I am aware
of the r.recode function, but I would like to do this conversion in a batch
mode. Can rules for r.recode be defined in a batch mode? Is there any other
method to do the conversion?
Thanks,
-amar
