Ah, could that be Abs Normal Form that you were talking about?

I tried ```jl @inline function rrule(::typeof(*), x::Number, y::Number) @inline function times_pullback(ΔΩ) return (NO_FIELDS, ΔΩ * y', x' * ΔΩ) end return x * y, times_pullback end ``` which seems to...

Thanks. What's the issue with `z^3`?

It seems like this should be solved by using `IJulia` to work out where the `jupyter` executable is.

This looks like a great example of the classic problem with interval arithmetic, namely the **dependency problem**. This occurs when you have have the same variable appearing >1 time in...

What's the status here? Should we merge this?

Usually things like the interval Newton method require that $N(X)$ is in the *interior* of $X$ for the conclusion to hold.

I don't think we implemented `sincospi`, so it's probably falling back to the generic version. (I didn't even know there was such a function.) Try splitting that up into two...

Note that there is only partial support for complex intervals so far.

@JeffreySarnoff: Do you have any thoughts about directed rounding for `fma`?
