<p>Is there a way to initialize an integer greater than 64 bits using the big package? The NewInt function takes an int64 as a parameter... It seems strange to me that you can't initialize an int greater than 64 bits, but a big.Int type can hold integers greater than 64 bits</p>

I've got it working now. Thanks a lot</p></pre>Bake_Jailey: <pre><p>I bet you could also get away with something like a combination of <code>NewInt(...)</code> and <code>Lsh(64).Or(...)</code>, which may be faster than the decode cost, but I haven't tested it, and you may not care about the performance implications (or you don't need this at all and you're just curious :P).</p></pre>
