--- Comment #2 from Sanjay Patel <spatel at rotateright dot com> ---
This is on plain x86-64 with SSE (before the addition of any FMA instructions),
so lack of FMA must be accounted for?
The answers differ in the last digit / ULP. Is there some standard or golden
implementation that will answer which answer is correct?
