Changing signifocant digits

From:"Stephen Duffull" Subject:[NMusers] Changing signifocant digits Date:Mon, 22 Jul 2002 12:13:33 +1000 Hi I have a general question. I recall hearing that changing the number of significant digits somehow changes the minimisation route. I do not understand how this is so. Oddly I have noticed that changing sig digits from say 3 to 4 can result in a successful minimisation for 4 whereas for 3 digits it did not. Any comments would be appreciated.
