R- exp(-1000) ? - how to get R to give me an actual answer ?

We can double check this with yacas which is a free
computer algebra system that supports arbitrary
precision math:

   In> N(Exp(-1000))
   Out> 0.5075958898e-434

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.

Thanks
