If i remember right, this switch goes back in history to the 8087. There was a
big fight, especially from astronomers and physicists, who wanted to trap the
hardware error on big numbers and run altenative math macros (such as
string math) on them, whereas everyone else said why bother. Ditto for "INF
+1 = INF -1" and other things i can't figure out.
