Not easily, but take a look at my code sample here: http://www.alexfeinman.com/download.asp?doc=GridDemo2.zip
The helper class Binder takes an optional Format parameter. If you specify
it as "#.00", you should get what you need.
I haven't revisited this sample since I written it in 2003, so it might not
work out of the box with SP3, but most likely will
