Thanks Earl
Thats exactly what I was looking for - an extension that uses libgmp and
provides a bignum type that can be combined with standard operators and
numeric variables. Somehow my original search on CRAN missed this one.
Cheers

Try this:

Probably not helpful for your particular problem, but the package rcdd
also has a fairly limited interface to the GNU MP Bignum library.
It does arithmetic on arbitrary precision rationals. Also exact linear
programming and computational geometry using arbitrary precision rationals.

Have a look at the Ryacas package which interfaces R to yacas.
yacas can do exact arithmetic.

One way of "doing it in R" is to use the 'bc' command that is on most
UNIX/LINUX systems and is also on cygwin for Windows. Here are
decimal digits for 2^1000
/cygdrive/c/jph/consulting/2008-03-30: bc
bc 1.06

Hi
(If you're wondering, this is a Project Euler question :))
If I wanted to calculate the sum of the digits in the decimal representation
of 2^1000, what would be a good way to go about that? I've tried the
following methods:
# Calculate the sum of digits in the decimal representation of 2^n
