mindspore.numpy.signbit

mindspore.numpy.signbit(x, dtype=None)[source]

Returns element-wise True where signbit is set (less than zero).

Note

Numpy arguments out, where, casting, order, subok, signature, and extobj are not supported.

Parameters

x (Union[int, float, bool, list, tuple, Tensor]) – The input value(s).
dtype (mindspore.dtype, optional) – Default: None . Overrides the dtype of the output Tensor.

Returns

Tensor.

Raises

TypeError – If input is not array_like or dtype is not None or bool.

Examples

>>> import mindspore.numpy as np
>>> x = np.array([1, -2.3, 2.1]).astype('float32')
>>> output = np.signbit(x)
>>> print(output)
[False  True False]
