Why can’t we do Uint64 class inside Math namespace to be used for all the
64-bit arithmetic operations?
Like:
var x = Math.Uint64(2);
var y = Math.Uint64.fromString(“0x12345678abcdef01”);
var z = x.mul(y); // or
That's strange. I believe I replied to different thread. Sorry.

There's no particular reason not to do something like that, except:
1. It is not usable (see
http://www.jroller.com/cpurdy/entry/the_seven_habits_of_highly1%23comment-1130764636000).
2. Math is becoming a dumping ground, as noted up-thread.
3. Polyfillability is not important if old code can

That is the difficulty in distinguishing positive and negative numbers

Unfortunately Claude, ES Math.sign is not Signum; it has five outputs, not
three, like Oliver was asking about. Observe:
Math.sign(1 / 0)
1
Math.sign(-1 / 0)
-1
Math.sign(-1 / 0 * 0)
NaN
Math.sign(0 * -1)
-0

`Math.sign` is expected to represent the mathematical sign
function, which has a precise definition, see [1], [2].
Please note that `+0` and `-0` are the same value as far as
maths is concerned, and that value is neither positive nor
negative. (Or both nonnegative and

At the very least, I think Oliver has a point in that it'd be very
useful to have a sign function which would return 1 for +0 and -1
for -0. I've needed this in the past. If it shouldn't be `Math.sign`,
perhaps there should be a `Number.sign` which would match the other
