A bit outside the scope of the question but `Float64 <: Union{Float64, Missing}` does the latter. See also [this post](https://discourse.julialang.org/t/get-non-missing-type-in-the-case-of-parametric-type/29109/4) on retrieving the non-missing type and corresponding pointer to [Missings.jl](https://github.com/JuliaData/Missings.jl).
