# doubles A cloned data column of doubles. ``` var doubles: MLDataColumn? { get } ``` ## Return Value A new data column if the underlying type of the column is ; otherwise `nil`. ## Discussion This property is functionally equivalent to passing `.self` to [`column(type:)`](/documentation/CreateML/MLUntypedColumn/column(type:)). Typically you ensure [`type`](/documentation/CreateML/MLUntypedColumn/type) is equal to [`MLDataValue.ValueType.double`](/documentation/CreateML/MLDataValue/ValueType/double) before getting this property. --- Copyright © 2026 Apple Inc.
