Behavior of convert

[rleegates]

Is this behavior intended and wanted?

julia> convert(SVector{3,Float64},rand(SVector{3,Int}))
3-element StaticArrays.SVector{3,Float64}:
  5.00727e18
 -2.74974e18
 -1.37507e18

I think so. What is it that you find odd about this?

To expand out the behavior:

julia> v = rand(SVector{3,Int})
3-element SVector{3,Int64}:
 -8557660434043172070
  6108837298082502987
 -4334229712641791305

julia> convert(SVector{3,Float64}, v)
3-element SVector{3,Float64}:
 -8.55766e18
  6.10884e18
 -4.33423e18

We also have

julia> convert(Float64, rand(Int))
8.593402832541683e18

I think this is intentional.

It should also match the base array types:

julia> v = rand(Int, 3)
3-element Array{Int64,1}:
 6535532840261742524
 1289793510179775070
 4638388731794814437

julia> convert(Vector{Float64}, v)
3-element Array{Float64,1}:
 6.535532840261743e18
 1.289793510179775e18
 4.638388731794814e18
