float(SVector) gives an MVector

[stevengj]

julia> float(SVector(0))
1-element MVector{1,Float64}:
 0.0

This is because it is calling base/float.jl, which calls convert(AbstractArray, ...) which calls similar, I think(?), but in this case it seems more useful to return an SVector?

Or is there a better way to promote an SVector to a float-based type, e.g. from Complex{Int} to Complex{Float}?

How about

float.(SVector(0))

I guess we should just add the following as a general solution:

float(a::StaticArray) = map(float,a)

Perhaps this would also be a better solution for Base for AbstractArrays of non-floats.

I think this one is fixed, perhaps by #747?

julia> float(SVector(0))
1-element SArray{Tuple{1},Float64,1,1} with indices SOneTo(1):
 0.0
