I tried a simple test on jsperf to see if I can get a speedup from float64 arrays:
http://jsperf.com/float64-vs-float In this test, using float64 arrays end up slower than just using normal variables. JSPerf tests are only run for a few seconds - is that long enough for v8's optimizer to kick in properly? - Or is that benchmark correct, and I'm just missing something? -J On Friday, 30 December 2011 07:33:14 UTC+11, Vyacheslav Egorov wrote: > > 2) There are fields mutated in the loop that contain floating point > values.
