+Manipulation of integers and their bits

+
+## [numpy.ndarray.byteswap](https://numpy.org/doc/stable/reference/generated/numpy.ndarray.byteswap.html)
+
+```python
+ndarray.byteswap(inplace=False)
+```
+
+> Swap the bytes of the array elements
+> 
+> Toggle between low-endian and big-endian data representation by returning a byteswapped array, optionally swapped in-place. Arrays of byte-strings are not swapped. The real and imaginary parts of a complex number are swapped individually.
+>
+> **inplace** : bool, optional
+> 
+> If True, swap bytes in-place, default is False.
+
+
+## [numpy.bitwise_and](https://numpy.org/doc/stable/reference/generated/numpy.bitwise_and.html)
+
+```python
+numpy.bitwise_and(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj])
+```
+
+> Compute the bit-wise AND of two arrays element-wise.
+> 
+> Computes the bit-wise AND of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator &.
+
+
+## [numpy.bitwise_or](https://numpy.org/doc/stable/reference/generated/numpy.bitwise_or.html)
+
+```python
+numpy.bitwise_or(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) 
+```
+
+>  Compute the bit-wise OR of two arrays element-wise.
+>  
+> Computes the bit-wise OR of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator \|.
+
+## [numpy.bitwise_xor](https://numpy.org/doc/stable/reference/generated/numpy.bitwise_xor.html)
+
+```python
+numpy.bitwise_xor(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj])
+```
+
+> Compute the bit-wise XOR of two arrays element-wise.
+> 
+> Computes the bit-wise XOR of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator ^.
+
+## [bitwise_not](https://numpy.org/doc/stable/reference/generated/numpy.invert.html)
+
+> **bitwise_not is an alias for invert**
+
+```python
+numpy.invert(x, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj])
+```
+
+> Compute bit-wise inversion, or bit-wise NOT, element-wise.
+> 
+> Computes the bit-wise NOT of the underlying binary representation of the integers in the input arrays. This ufunc implements the C/Python operator ~.
+> 
+> For signed integer inputs, the two’s complement is returned.
