I’m interested in solving semidefinite optimization problems and compute the derivatives of the solutions w.r.t. input parameters. BigFloat may be needed for some of the more demanding problems. Does the differentiable optimization package [DiffOpt.jl](https://github.com/jump-dev/DiffOpt.jl) work with the arbitrary-precision semidefinite solver [SDPAFamily.jl](https://github.com/ericphanson/SDPAFamily.jl)?

I’m not sure if anyone has tried, but a search for `Float64` in the repo returns a lot of hits, [Search · Float64 · GitHub](https://github.com/jump-dev/DiffOpt.jl/search?q=Float64&type=), so perhaps not.

Nevertheless, perhaps try, and open an issue at DiffOpt.jl if you run into problems.
