Comment #20 on issue 3903 by [email protected]: Math.log10 is unexpectedly
slow
https://code.google.com/p/v8/issues/detail?id=3903
Thanks!
From your new code, I think that your cached and inlined reinterpret cast
stuff is probably very close to what V8 is currently doing. V8 has
inlined/optimized _DoubleHi, _DoubleLo, and _ConstructDouble functions.
Perhaps the difference between Math.log10 and log10rtoyJS(c)(n) is due to
slight differences in _DoubleHi and friends.
