torch.signbit¶

torch.signbit(input, *, out=None) → Tensor¶

Tests if each element of input has its sign bit set (is less than zero) or not.

Parameters: input (Tensor) – the input tensor.
Keyword Arguments: out (Tensor, optional) – the output tensor.

Example:

>>> a = torch.tensor([0.7, -1.2, 0., 2.3])
>>> torch.signbit(a)
tensor([ False, True,  False,  False])
