Dear All,

I am a novice user of the R software package. When I try and compute, 
exp(-1000) or exp(-2000), i get the answer as zero. Is there any way i can get 
R to compute the answer and give me an actual number ? ( by increasing the 
precision or any other method).

If I cannot get R to give me a number, can anybody give me some advice on how 
to manually compute this number ?

I would greatly appreciate your help on this issue.
