larray.signbit¶

larray.
signbit
(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj])¶ Returns elementwise 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 freshlyallocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.
 wherearray_like, optional
This condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default
out=None
, locations within it where the condition is False will remain uninitialized. **kwargs
For other keywordonly 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])
