I'm getting the same answer "1" for Exp[x] with x less than "1.1*10^-16", and I really need to calculate much smaller numbers (in order of 10^-40).
I tried using SetPrecision[Exp[x],1000].
Obviously I'm doing something wrong. #_-
I've searched about increasing the precision but I couldn't find helpful answers. Would you please kindly guide me?
Maybe this screenshot could make it easier to understand what I'm talking about.
