I’m looking at the package [SDPAFamily.jl](https://github.com/ericphanson/SDPAFamily.jl) which provides access to arbitrary-precision semidefinite programming solvers. The README says that the JuMP interface does not support BigFloat. Is it still possible to somehow use the package “directly”, with BigFloat input / output?

You can use `BigFloat` through the Convex.jl interface:

- [Home · Convex.jl](https://jump.dev/Convex.jl/stable/)
- [GitHub - ericphanson/SDPAFamily.jl: A Julia interface to the SDPA-GMP, SDPA-DD, and SDPA-QD high precision semidefinite programming solvers.](https://github.com/ericphanson/SDPAFamily.jl#quick-example)
