# atanh

[common]\
fun [atanh](atanh.md)(input: [Tensor](../Tensor/index.md)): [Tensor](../Tensor/index.md)

`atanh(input: Tensor)`: the `atanh` operator. Elementwise inverse hyperbolic tangent. Inputs outside `(-1, 1)` produce NaN / ±inf. Value-domain violations follow IEEE semantics (NaN / ±inf in the result), never an error.
