Why is SSE scalar sqrt(x) slower than rsqrt(x) * x?
...
This is also true for division. MULSS(a,RCPSS(b)) is way faster than DIVSS(a,b). In fact it's still faster even when you increase its precision with a Newton-Raphson iteration.
Intel and AMD both recommend this technique in their optimisation manuals. In applications which don't require IEEE-...

Are the shift operators () arithmetic or logical in C?
...es.
Basically you need to either test your compiler or not rely on it. My VS2008 help for the current MS C++ compiler says that their compiler does an arithmetic shift.
