# forge.ta.nz

```python
forge.ta.nz(x: ArrayLike | float | None, value: float = 0.0) -> np.ndarray[Any, Any] | float
```

Replace a missing value with ``value`` (default 0).

A scalar ``None`` or ``NaN`` gives ``value``. A float array gives a new float64
array and never changes the input. Boolean and integer arrays carry no missing
value, so a copy comes back unchanged.
