Can't find any documentation on this:

(*avoid use of high - precision arithmetic*)
Developer`SetSystemOptions["CatchMachineUnderflow" -> False]

Spotted while reading Trott's Mathematica guidebook for programming.
Why I think it could be important to me is because my particles as they
come close would cause huge repulsion and that would be due to a
mistake in the program, and I'd prefer an error message just like
runtime for C-program. 
Any comment?
