So, where are your 128 bit SSE instructions? What compiler? What language? Interestingly, Intel's own compiler, when operating on int128, does not emit these instructions you claim exist (you can check it on Godbolt.org and look at disassembly). Maybe you should tell them about these instructions. Why does your routine fail for simple cases that the floating point does not? Please stop deflecting. Can you post code, compiler, and language or not? >Really? So now we've progressed from $100 thousand to $100 million to the national budget? That example is for a $100,000 future value where your algorithm fails. It is not national budget. Did you even try the examples I demonstrated where your algorithm fails? >By the standard you're applying, your own algorithm itself is equally "bad". Yet it's incredibly faster, does not rely on lying about mythical instruction sets, and handles simple cases yours didn't, even cases you claimed yours did handle. Oh, and it uses honest 64 bit hardware. So, code and compiler to demonstrate your SSE claims, or this thread has demonstrated what I expected it to.
