This implementation is based on primo's comprehensive description of the algorithm he used.

for(e=l=x=prompt(g=1e5);--g;y=x-1,l=(x>1?y/=x:-y)*l+y/g)
    e=1+e/g*x;
alert([e,x>0?l:"ERROR"])

Edit:
- Trying to catch Perl. Stole a byte back from primo by copying his branch. :)
- 2 more bytes courtesy of primo.
- Finally, caught primo's version! With primo's help, of course... :)
- Simplified the assignment to L. Shaved 3 more bytes.
