# acosInPlace

[common]\
fun [acosInPlace](acosInPlace.md)(self: [Tensor](../Tensor/index.md)): [Tensor](../Tensor/index.md)

`acosInPlace(self: Tensor)`: the `acos_` operator. In-place `acos`: writes the result through `self`; same formula, arguments, and error conditions as `acos()`. A view input writes through its base storage. Returns `self` under the value surface, `Result<void>` under the `Result` surface; `CLIKART_CHECK` is the mode-stable spelling. Writes through `self` and returns it, so calls chain.
