Just tried in the console of Chrome (with "Experimental JavaScript features" flag enabled).
> Math.log2(8)
< 2.9999999999999996
Firefox gives me the correct answer (3).
Question: Should Math.log2 give exact results for powers of 2?
The same issue holds for Math.log10 (might be applicable for nonnegative powers only): Math.log10(1e15) != 15 in Chrome.
