List-
I've got a calculation that, due to its use of exp(), is produces double precision intermediate results which I ultimately need to cast back to real to store in a table column. However, with certain inputs, this results in an underflow error. Is there any way outside of an exception-trapping plpgsql function to performance the conversion and simply cause underflows to result in a 0?
Thanks for any ideas.
