## cast\_like() {#cast_like}

<div class="api-signature">

[`Tensor`](../Tensor.md) **`cast_like`**([`Tensor`](../Tensor.md) `input`, [`Tensor`](../Tensor.md) `reference`)

</div>

[`cast`](./cast.md#cast) to another tensor's dtype: [`cast`](./cast.md#cast)`(x, reference.dtype())`.

**Throws**

- `ClikaRT::Error`: when the input's dtype/shape is not served for this operation (the machine-readable reason rides `code_name()`).

**Returns:** `input` converted to `reference`'s dtype; same shape as `input`.
