# type

The underlying type of the column.

## Declaration

```swift
var type: MLDataValue.ValueType { get }
```

## Discussion

Discussion Use this to determine the underlying type of the column. Then use a corresponding property or method to create an MLDataColumn of the untyped column. For example, if type is equal to MLDataValue.ValueType.double, then use the MLUntypedColumn doubles property.
