# MLMultiArrayDataType

Constants that define the underlying element types a multiarray can store.

```
enum MLMultiArrayDataType
```

## Overview

All elements of an [`MLMultiArray`](/documentation/CoreML/MLMultiArray) instance must be of the same type and must be defined in [`MLMultiArrayDataType`](/documentation/CoreML/MLMultiArrayDataType).

## Topics

### Multiarray data types

[`MLMultiArrayDataType.int8`](/documentation/CoreML/MLMultiArrayDataType/int8)

[`MLMultiArrayDataType.int32`](/documentation/CoreML/MLMultiArrayDataType/int32)

Designates the multiarray’s elements as 32-bit integers.

[`MLMultiArrayDataType.float16`](/documentation/CoreML/MLMultiArrayDataType/float16)

Designates the multiarray’s elements as 16-bit floats.

[`MLMultiArrayDataType.float32`](/documentation/CoreML/MLMultiArrayDataType/float32)

Designates the multiarray’s elements as 32-bit floats.

[`MLMultiArrayDataType.double`](/documentation/CoreML/MLMultiArrayDataType/double)

Designates the multiarray’s elements as doubles.

[`float`](/documentation/CoreML/MLMultiArrayDataType/float)

Designates the multiarray’s elements as floats.

[`float64`](/documentation/CoreML/MLMultiArrayDataType/float64)

Designates the multiarray’s elements as 64-bit floats.
