Re: Power operator, why does -2**3 throws?

This "should" be correct in the context of correct mathematics. Expectations and correctness must bias toward correctness. Math/Algebra has been one of the weak points of the web so it makes sense to toss an error and demand the programmer make his intention clear. It also helps with testing to

Re: Power operator, why does -2**3 throws?

If -2 ** 2 returned me -4 in JS I would be confused. JS is not a math language, it's a programming language. We have basic math operations on its syntax and that's fine. > In the same vein, you have `pow(1+1, 2) == 4` but `1+1 ** 2 == 2`, because the latter is interpreted as `1+(1 ** 2)`. Where

Re: Power operator, why does -2**3 throws?

I was testing something https://caub.github.io/misc/calculator, and I didn't see how it would be a problem to have the precedence of ** higher than unaries. But at least I'm happy something like (2).pow(3) wasn't chosen. Thanks anyway and sorry for discussing something already frozen in spec

Re: Power operator, why does -2**3 throws?

Ah, ok, a bit sad because all more scientific languages, and python too, all math books, all will use `-e^3` for meaning `-(e^3)` (^ or **), because it's just `-exp(3)` or `-pow(E, 3)` and `(-1)^n` otherwise, when we want to take the signs with. If you wanted to avoid any confusion you could

What does it change if it handles floats? I just checked https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Operator_Precedence unary + is 16, while exponentiation is 15, so the opposite order that I thought 2016-10-14 13:37 GMT+02:00 J Decker : >

probably because it's floating point native not integer like you'd think, so -2.0001 ** 3 is hard? On Fri, Oct 14, 2016 at 4:30 AM, Cyril Auburtin wrote: > I would expect `-2**3` to return -8, or `-2**2 == -4`, since it should be > like `-(2**3)` > > Firefox gives

Power operator, why does -2**3 throws?

I would expect `-2**3` to return -8, or `-2**2 == -4`, since it should be like `-(2**3)` Firefox gives a clearer error then Chrome with: > SyntaxError: unparenthesized unary expression can't appear on the left-hand side of '**' Is there a reason for this restriction? Python does it `-2**3` fine
