Consider the following interaction:
julia> g(x) = 1 / (1 + x)
g (generic function with 1 method)
julia> typeof(g(1.0))
Float64
julia> xs = [1.0, 2.0, 3.0, 4.0]
4-element Array{Float64,1}:
1.0
2.0
3.0
4.0
julia> gxs1 = [g(x) for x in xs]
4-element Array{Any,1}:
0.5
0.333333
0.25
0.2
Why isn't gxs1 type of Array{Float64,1}?
How could I force the type of gxs1 to be of an array of Float64?
julia> gxs2 = [convert(Float64,g(x)) for x in xs]
4-element Array{Any,1}:
0.5
0.333333
0.25
0.2
somehow this doesn't seem to work...
