Charles:
Your function misses a special case. If the negative number is an integer, you wouldn’t want to subtract 1 from trunc(theNegativeNumber).

If the bunch of us have created a new, valuable and effective, if esoteric, function, then it would be nice to include it somewhere so that it doesn't have to be recreated every few months... Or maybe it should be en enhancement request? I guess I'm not clear on that.
