positive#

ivy.positive(x, /, *, out=None)[source]#

Return a new array with the positive value of each element in x.

Parameters:

  • x (Union[float, Array, NativeArray]) – Input array.

  • out (Optional[Array], default: None) – optional output array, for writing the result to. It must have a shape that the inputs broadcast to.

Return type:

Array

Returns:

ret – A new array with the positive value of each element in x.

This function conforms to the Array API Standard. This docstring is an extension of the docstring in the standard.

Both the description and the type hints above assumes an array input for simplicity, but this function is nestable, and therefore also accepts ivy.Container instances in place of any of the arguments

Examples

With ivy.Array input:

>>> x = ivy.array([2, 3 ,5, 7])
>>> y = ivy.positive(x)
>>> print(y)
ivy.array([2, 3, 5, 7])

>>> x = ivy.array([0, -1, -0.5, 2, 3])
>>> y = ivy.zeros(5)
>>> ivy.positive(x, out=y)
>>> print(y)
ivy.array([0., -1., -0.5,  2.,  3.])

>>> x = ivy.array([[1.1, 2.2, 3.3],
...                [-4.4, -5.5, -6.6]])
>>> ivy.positive(x,out=x)
>>> print(x)
ivy.array([[ 1.1,  2.2,  3.3],
   [-4.4, -5.5, -6.6]])

With ivy.Container input:

>>> x = ivy.Container(a=ivy.array([0., 1., 2.]),
...                   b=ivy.array([3., 4., -5.]))
>>> y = ivy.positive(x)
>>> print(y)
{
a: ivy.array([0., 1., 2.]),
b: ivy.array([3., 4., -5.])
}
Array.positive(self, *, out=None)[source]#

ivy.Array instance method variant of ivy.positive. This method simply wraps the function, and so the docstring for ivy.positive also applies to this method with minimal changes.

Parameters:

  • self (Array) – input array. Should have a numeric data type.

  • out (Optional[Array], default: None) – optional output, for writing the result to. It must have a shape that the inputs broadcast to.

Return type:

Array

Returns:

ret – an array containing the evaluated result for each element in self. The returned array must have the same data type as self.

Examples

With ivy.Array input:

>>> x = ivy.array([2, 3 ,5, 7])
>>> y = x.positive()
>>> print(y)
ivy.array([2, 3, 5, 7])

>>> x = ivy.array([0, -1, -0.5, 2, 3])
>>> y = ivy.zeros(5)
>>> x.positive(out=y)
>>> print(y)
ivy.array([0., -1., -0.5,  2.,  3.])

>>> x = ivy.array([[1.1, 2.2, 3.3],
...                [-4.4, -5.5, -6.6]])
>>> x.positive(out=x)
>>> print(x)
ivy.array([[ 1.1,  2.2,  3.3],
[-4.4, -5.5, -6.6]])
Container.positive(self, *, key_chains=None, to_apply=True, prune_unapplied=False, map_sequences=False, out=None)[source]#

ivy.Container instance method variant of ivy.positive. This method simply wraps the function, and so the docstring for ivy.positive also applies to this method with minimal changes.

Parameters:

  • self (Container) – input container. Should have a numeric data type.

  • key_chains (Optional[Union[List[str], Dict[str, str], Container]], default: None) – The key-chains to apply or not apply the method to. Default is None.

  • to_apply (Union[bool, Container], default: True) – If True, the method will be applied to key_chains, otherwise key_chains will be skipped. Default is True.

  • prune_unapplied (Union[bool, Container], default: False) – Whether to prune key_chains for which the function was not applied. Default is False.

  • map_sequences (Union[bool, Container], default: False) – Whether to also map method to sequences (lists, tuples). Default is False.

  • out (Optional[Container], default: None) – optional output container, for writing the result to. It must have a shape that the inputs broadcast to.

Return type:

Container

Returns:

ret – a container containing the evaluated result for each element in self. The returned container must have the same data type as self.

Examples

With ivy.Container input:

>>> x = ivy.Container(a=ivy.array([0., 1., 2.]),
...                   b=ivy.array([3., 4., -5.]))
>>> y = ivy.positive(x)
>>> print(y)
{
    a: ivy.array([0., 1., 2.]),
    b: ivy.array([3., 4., -5.])
}
