When I tried the following command to generate 2-dims linspace arrays, whose type should be `Float`, not `Int`

```julia
r = range([1,1],[8,9],length=10)
# 10-element LinRange{Array{Int64,1}}:
# [1.0, 1.0],[1.77778, 1.88889],[2.55556, 2.77778],…,[7.22222, 8.11111],[8.0, 9.0]

```

and when I access `r[2]`, it throws

> ERROR: InexactError: Int64(1.7777777777777777)

But the `LinRange` works well,

```julia
lr = LinRange([1,1],[8,9],10)
# 10-element LinRange{Array{Float64,1}}:
# [1.0, 1.0],[1.77778, 1.88889],[2.55556, 2.77778],…,[7.22222, 8.11111],[8.0, 9.0]

```

So I am wondering if this is a possible bug returned by `range` in 2-dims case.

You told `range` to use `Ints`.

> 10-element LinRange{Array{Int64,1}}:

Do this instead.

```julia

julia> r = range([1.0,1.0],[8.0,9.0],length=10)
10-element LinRange{Array{Float64,1}}:
 [1.0, 1.0],[1.77778, 1.88889],[2.55556, 2.77778],…,[6.44444, 7.22222],[7.22222, 8.11111],[8.0, 9.0]

julia> r[3]
2-element Array{Float64,1}:
 2.5555555555555554
 2.7777777777777777

```

Thank you for your response. Actually, I have tried that way. But I am curious about the different behaviors of `range` and `LinRange`.

always good to start with the docs

Thank you for your advice.

Actually, because I know that for 1-dim case, `range(1, 8, length=10)` would not be restricted to `Int`, and it is OK to access the second Float element. But for 2-dim case, it fails. So I am a little confused.

I am not sure `range` was intended to work with non-scalar arguments.
