Hi John,
Thanks for your reply, I'm getting the following:
julia> A=DataArray([1 2; 3 4])
2x2 DataArray{Int64,2}:
1 2
3 4
julia> A*.5
2x2 DataArray{Float64,2}:
0.5 1.0
1.5 2.0
julia> A/2.
2x2 DataArray{Float64,2}:
0.5 1.0
1.5 2.0
julia> A/2
InexactError()
So it converts to Float if divided by Float, but does not convert if
divided by Integer.
Best,
Bradley
