replying to an old thread:
It looks like I reused code/ideas from r.example which does it that way.

Right.
We should consider whether that idiom is appropriate for an example
module. Most modules only use a single data type (typically CELL if
the functionality is only meaningful for integers, or DCELL
otherwise).
Many of the r.mapcalc functions have three versions, but the FCELL
cases are mostly pointless (most of them actually use double then
truncate the result).
