I fully support this idea.
I think this would be a very important for the future of Grass.
When I spoke to Peter Burrough at EGIS this spring he though this was
the main week point in Grass.  I have helped some people with watershed 
models and it would have been very useful with float values.  Personally
I think I miss the the difference between null and zero data the most.
Float values you could allways use multiply factors instead even if it
is a hazzle.
