That was an interesting exchange.
I agree that there's probably no immediate benefit from translating the
libm into julia, but as an exercise it might have some indirect benefits:
* It could provide a sort of gold standard of julia numeric code for
people who are interested in poking around and
Very nice, Simon. That's super cool. Would love to have some of these gems
in Base Julia. With good documentation of how they can be used would be a
really valuable combination that's actually quite hard to find anywhere.
These kinds of tricks and the expertise to use them tend to be scattered

That's a very slick JavaScript app. The interactive plotting is really very
nice. The mathy input widget is great too. JavaScript certainly has the
performance these days to make this stuff work – and as long as you stick
to 64-bit floats, things are probably all good, unless someone decides to
If you love the details of floating point math, may I humbly recommend

This isn't so Julia related, per se, but I find it fascinating, and can't
think of a better place to find other people who might also.
Here's my TLDR:
1. Someone
Interesting. I'm not sure how bad the function call overhead in JavaScript
is (or why it would be bad), but for us it's the same as one C function
calling another C function. The main advantages of reimplementing things in
pure Julia are: (a) generalization – same algorithm can apply to many
Interesting. On my chrome (37.0) at least, I can go up a few orders of
magnitude to Math.sin(-1e16) still getting zero back.

Someone once asked me about using JavaScript for numerical computing.

Numerical computing with javascript is my day job: https://www.desmos.com/.
I got interested in this whole saga because our unit tests started failing.
