Dear all, I have an Int array and Float64 array. And I want to merge them. julia> a =[1, 2, 3]; julia> b =[1.0, 2.0, 3.0]; julia> A =hcat(a, b) 3×2 Matrix{Float64}: 1.0 1.0 2.0 2.0 3.0 3.0 Here I get a Float64. But I want the first column to be Int64. The result I want is 1 1.0 2 2.0 …

julia> A = Union{Int,Float64}[a b] 3×2 Matrix{Union{Float64, Int64}}: 1 1.0 2 2.0 3 3.0

Question about Float64 and Int?

In my codes, It seems that Union is faster than hcat.
