[R] Problem with long number (from character to numeric class)

Hello,

I have a text file with one column containing long number but stored as
string.
I download the file with read.table (and colClass) and the first row of this
column is :

"095842087016731010"

As I need to make some calculations with these numbers, I tried to convert
them using as.numeric.
But then I get
as.numeric("095842087016731010")
95842087016731008

I understand the disappearing of the first 0 but I don't understand the
substitution of the last 0 by 8.

Is there a way to avoid that ?
Thanks in advance,
Ptit Bleu.
