Maybe I'm doing it wrong, but it looks like there is a problem with airyaiprime and BigFloats:

For OPs on `y⁴ = 1 - x⁴` I need conversion operators between `ChebyshevT()` and certain semiclassical OPs, e.g.,
```julia
T = ChebyshevT{BigFloat}()
x = axes(T,1)
P₁ = LanczosPolynomial( (1 .+ x.…

`BigFloat` could be moved to a stdlib package (`BigFloats`? `MPFR`?), though there are a few places it is coupled to Base:
- [ ] `widen(::Float64)` and `big(::AbstractFloat)`
* Should we just leav…

if I do a string-categorical sortval I run into the error below.
MWE:
```julia
plot_erpimage(rand(5,10),sortvalues=string.(1:10),show_sortval=true)

In well spread open source numerical c libraries such as [`gmp`](https://gmplib.org/), [`mpfr`](http://www.mpfr.org/), a [conventional construct](http://www.mpfr.org/mpfr-current/mpfr.html#Nomenclatur…

The mpmath provides global [context objects](https://mpmath.readthedocs.io/en/latest/contexts.html) (mp, fp, iv). Most functions in the global mpmath namespace are actually methods of the mp context.…

Currently, I don't see a way to extract the real value wrapped up in `ArrayBox` typed variable. This would be convenient if one would like to use a package with higher precision. I.e. if one wants to …

Last week I had some discussion in a PR to Distributions about the design of `rand` (https://github.com/JuliaStats/Distributions.jl/pull/1262#issuecomment-764995042), and I think it applies to Measure…

`big(1.3)^(1//7)` currently converts the rational to `BigFloat` before computing the power, thereby losing accuracy.
It should instead use the specialised MPFR function `mpfr_rootn_si`.

We just found a very strange behavior for BigFloat. The BigFloat(2.1) always shows 2.0 as result. However, when we tried BigFloat(2.1)-BigFloat(2.0), we can see BigFloat(2.1) actually has been convert…
