specialized arithmetic and in-place functions

8

by doing `promote` stuff simple arithmetic allocates a lot: ```julia julia> z = ArbComplex(2) 2.0 + 0im julia> @time z+1; 0.000023 seconds (11 allocations: 600 bytes) ``` by exploiting `arb`s...

`slong` : `Cint` or `Clong`?

1

I guess arbs `slong` translates to `Clong` on the julia side: ```julia julia> w = typemax(Cint) +1 2147483648 julia> ArbComplex(w) ERROR: InexactError: trunc(Int32, 2147483648) (...) julia> z = ArbComplex{128}() 0...

integration

Arb has [acb_calc](http://arblib.org/acb_calc.html), where `acb_calc_integrate` is provided. I tried to wrap the function as follows ```julia #src/float/integrate.jl struct acb_calc_integrate_opt_struct deg_limit::Cint #slong eval_limit::Cint #slong depth_limit::Cint #slong use_heap::Cint #int verbose::Cint #int function...

Allow defining callable types in different cells as the struct definition

Sorry, but there will be no video for this one, It's literally too simple ;) Happens with ```julia [c3e4b0f8] Pluto v0.19.0 ``` Consider the following code: ```julia julia> struct AAA...

this is using `v0.5.2` (current master) of [Groups.jl](https://github.com/kalmarek/Groups.jl) ``` julia> using Groups [...] julia> let R = 9, F2 = Groups.FreeGroup([:a, :b, :c]) S2 = [gens(F2); inv.(gens(F2))] @time l3 =...

to check one element of #59 off https://github.com/kalmarek/PermutationGroups.jl is not battle tested, but achieves reasonable perf. It'd be great to have a serious user ;) ┆Issue is synchronized with this...

instability of SCS-2.0.x

19

I have a class of SD problems for which `SCS-1.2.6` was able to obtain a very accurate (1e-10) solution (albeit converging slowly), but `SCS-2.0.2` is not. SCS Logs show a...

While I see that title seems tautologic ;-) and that issue may very well be a feature, please consider the following example: ```julia X = Array{Float64}(2,2) X[1,1] = rand() X[2,1]...
