I can guess two possibilities: 1. One of you is using the binary I compiled, the other is using something different. Since mine shows 2 as the answer, I think Kjetil might be using mine. 2. One of you has had the floating point precision reduced by some buggy DLL or video driver. There are probably other explanations. The calculation is inherently unstable; it might be that Brian did it under a different phase of the moon, and that's why he got the "right" answer.
