Hi All,
thank you all for your help. I have tried Bill's script and it works! so I
am trying to think what was the problem and it looks like it i sthe
precision. so you defined a function of the precision and evaluates at
precision=500. Bill, I was wondering how did you choose 500? is it
arbitrar
I have added a FAQ to the r-bc home page which should help address
your problems in getting bc to work.

Hi All,
I was wondering if R can deal with high precsion numbers, below is an
example that I tried on using R and Maple where I got different results. I
was not able to use the r-bc package in R, instead I used the Rmpfr
package, below are both R and Maple results

Maybe bc(..., args = "") or perhaps install a more standard version of
bc. See links at http://r-bc.googlecode.com

Hi ,
Thanks for your help, I have been trying to use the bc package but I am
getting the following error
"Error in system(cmd, input = input, intern = TRUE) : -l not found"
any idea??

Hi All,
I was wodering if it is possible to increase the precision using R. I ran
the script below in R and MAPLE and I got different results when k is large.
Any idea how to fix this problem? thanks for your help
for (k in 0:2000){
s=0
for(i in 0:k){
s=s+((-1)^i)*3456*(1+i*1/2000)^3000
}
}
