Hi all !

Here is part of the standard. Required exception handling. Things I 
discuss in my post. Is it implemented in J? 
https://en.wikipedia.org/wiki/IEEE_754#Exception_handling
The floating point standard is obviously used in environments where the 
users can not afford random results, so there must be solutions to the 
problems I mention, which we also can see in this wikipedia article.

Cheers,
Erling
