On my laptop (newish, but 3 years old now) I can calculate it in almost no time at all: $ time ./fib 100000 >x ./fib 100000 > x 0.00s user 0.00s system 44% cpu 0.009 total $ wc x 1 1 20900 x > That is a 21033 digit number... so my approach to programming may not > be so bad afterall... I think you have a bug. The 100,000th Fibonacci number is 20,899 digits long. -- Ben.
