nlcpy.invert

nlcpy.invert = <ufunc 'nlcpy_invert'>

Computes the bit-wise NOT element-wise.

This ufunc implements the C/Python operator ~.

Parameters

xarray_like

Only integer and boolean types are handled. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).

outndarray or 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

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 keyword-only arguments, see the section Optional Keyword Arguments.

Returns

yndarray

y = ~ x. If x is a scalar, this function returns the result as a 0-dimension ndarray.

See also

bitwise_and

Computes the bit-wise AND of two arrays element-wise.

bitwise_or

Computes the bit-wise OR of two arrays element-wise.

bitwise_xor

Computes the bit-wise XOR of two arrays element-wise.

logical_not

Computes the logical NOT of the input array element-wise.

Examples

>>> import nlcpy as vp
>>> x = vp.invert(vp.array(13, dtype=vp.uint32))
>>> x
array(4294967282, dtype=uint32)

When using signed integer types the result is the two’s complement of the result for the unsigned type:

>>> vp.invert(vp.array([13], dtype=vp.int32))
array([-14], dtype=int32)

Booleans are accepted as well:

>>> vp.invert(vp.array([True, False]))
array([False,  True])
