[R] long integer handling

[Yousri Fanous]

I want to calculate 2^64-1 which is
18446744073709551615

I set the following options to prevent scientific notation
options("scipen"=100, "digits"=4)
> x<-2^64 -1
> x
[1] 18446744073709551616

This is not correct. There seem to be still some approximation happening.
How can I get the correct result?
