If you want to build a 128-bit int yourself, not using native types or existing code, then my approach would be to look at how it's done at a smaller scale, like 16-bit math on an 8-bit uC, e.g. http://www.8052.com/math - the same concepts apply when building a 128-bit number out of two 64-bit numbers.

By the way, if you like fractals then you've probably already seen this, but if not you may enjoy it: https://www.youtube.com/watch?v=foxD6ZQlnlU
