larray.signbit¶
-
larray.
signbit
(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj])¶ Returns element-wise True where signbit is set (less than zero).
larray specific variant of
numpy.signbit
.Documentation from numpy:
- Parameters
- xarray_like
The input value(s).
- outndarray, None, or tuple of ndarray 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 array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.
- wherearray_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
For other keyword-only arguments, see the ufunc docs.
- Returns
- resultndarray of bool
Output array, or reference to out if that was supplied. This is a scalar if x is a scalar.
Examples
>>> np.signbit(-1.2) True >>> np.signbit(np.array([1, -2.3, 2.1])) array([False, True, False])
