numpy.bitwise_and(x1, x2[, out]) =
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 &
.
Parameters: |
x1, x2 : array_like Only integer and boolean types are handled. |
---|---|
Returns: |
out : array_like Result. |

The number 13 is represented by 00001101
. Likewise, 17 is represented by 00010001
. The bit-wise AND of 13 and 17 is therefore 000000001
, or 1:
>>> np.bitwise_and(13, 17) 1
>>> np.bitwise_and(14, 13) 12 >>> np.binary_repr(12) '1100' >>> np.bitwise_and([14,3], 13) array([12, 1])
>>> np.bitwise_and([11,7], [4,25]) array([0, 1]) >>> np.bitwise_and(np.array([2,5,255]), np.array([3,14,16])) array([ 2, 4, 16]) >>> np.bitwise_and([True, True], [False, True]) array([False, True], dtype=bool)
