Math.log10

[Yaffle]

Math.log10(1e15) is 14.999999999999996 in Chrome 19

[paulmillr]

Do you propose to round the result?

The function uses just built-in js math funcs: Math.log(1e15) * 1 / Math.LN10 gives the same result.

[Yaffle]

rounding will not help

users of this shim should be informed...

[paulmillr]

I've added accuracy is 1e-11 to the readme.

[Yaffle]

how did you calculate this accuracy?

[paulmillr]

It's simple, it's the smallest accuracy when all math tests are passing.

Math.hypot(10e200, 0) - 10e200

[paulmillr]

and this is a bug in hypot. it should be probably for large numbers

function(x, y) {
  return Math.sqrt(x) * Math.sqrt(x) + Math.sqrt(y) * Math.sqrt(y);
};

[paulmillr]

meh, it gives incorrect result too

@paulmillr see https://gist.github.com/2427837 for "hypot" - http://www.netlib.org/fdlibm/e_hypot.c translated to js

[paulmillr]

great, thanks, i'll look at it & try to merge

[Yaffle]
