title: how do I declare an integer variable of 1024 bits in length?
body: <p>I'm trying to write an algorithm for a number theory/computer science merged class that can factor large numbers in better than exponential time. I am using the g++ compiler on a 64 bit machine but when I chain together <code>long</code> it will only allow me to do up to 2 longs. Is there any way to tell it to use an arbitrary amount of space for a variable? </p>
