maxframe.tensor.signbit#

maxframe.tensor.signbit(x, out=None, where=None, **kwargs)[source]#

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

Parameters:

x (array_like) – The input value(s).
out (Tensor, None, or tuple of Tensor and None, optional) – A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated tensor is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.
where (array_like, optional) – Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone.
**kwargs

Returns:

result – Output tensor, or reference to out if that was supplied.

Return type:

Tensor of bool

Examples

>>> import maxframe.tensor as mt

>>> mt.signbit(-1.2).execute()
True
>>> mt.signbit(mt.array([1, -2.3, 2.1])).execute()
array([False,  True, False])
