Comment #19 on issue 3006 by [email protected]: Inaccurate sin/cos
values
http://code.google.com/p/v8/issues/detail?id=3006
Issue 3043 is about the last bit being different. Four people have told you
that the new sin/cos implementation is WAI. How many more do you want?
Also, as you can guess from the fact that the new sin/cos implementation is
done in JavaScript anyway, it's trivially easy to experiment with your own
implementation(s). If you care so much, go ahead and play around with a
3-term Taylor series or any other method you can think of. If you can find
one that's at least as fast as the current built-in version while providing
better accuracy, we'd be more than happy to accept a patch :-)
Note that I'm intentionally putting speed before precision here. Also, "the
cost is probably comparable" doesn't quite cut it; I'd like to see hard
benchmark numbers.
