Is this a bug? A = sparse(Int32[], Int32[], Float64[], 2, 2) A + I # Loses Int32 A is of type SparseMatrixCSC{Float64,Int32} and A + I is of type SparseMatrixCSC{Float64,Int64}, losing the integer type. Thanks

UniformScaling with SparseMatrixCSC{T,Int32} loses integer type

Yes, - as well. And I + A also. All three are together in the code.
