# xarray.ufuncs.positive

### xarray.ufuncs.positive *= <xarray.ufuncs._unary_ufunc object>*

xarray specific variant of `numpy.positive()`. Handles xarray objects by dispatching to the appropriate function for the underlying array type.

Documentation from numpy:

Numerical positive, element-wise.

* **Parameters:**
  **x** ([array_like](https://numpy.org/doc/stable/glossary.html#term-array_like) or [scalar](../user-guide/terminology.html.md#term-scalar)) – Input array.
* **Returns:**
  **y** ([`ndarray`](https://numpy.org/doc/stable/reference/generated/numpy.ndarray.html#numpy.ndarray) or [scalar](../user-guide/terminology.html.md#term-scalar)) – Returned array or scalar: y = +x.
  This is a scalar if x is a scalar.

### Notes

Equivalent to x.copy(), but only defined for types that support
arithmetic.

```pycon
>>> import numpy as np
```

```pycon
>>> x1 = np.array(([1., -1.]))
>>> np.positive(x1)
array([ 1., -1.])
```

The unary `+` operator can be used as a shorthand for `np.positive` on
ndarrays.

```pycon
>>> x1 = np.array(([1., -1.]))
>>> +x1
array([ 1., -1.])
```
