bitwise_and
Compute the bit-wise AND of two tensors 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 &.
&
x1 (array_like) – Only integer and boolean types are handled.
x2 (array_like) – Only integer and boolean types are handled.
out (Tensor, None, or tuple of Tensor 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 tensor is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.
where (array_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 –
out – Result.

Examples
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:
00001101
00010001
000000001
>>> import mars.tensor as mt
>>> mt.bitwise_and(13, 17).execute() 1
>>> mt.bitwise_and(14, 13).execute() 12 >>> mt.bitwise_and([14,3], 13).execute() array([12, 1])
>>> mt.bitwise_and([11,7], [4,25]).execute() array([0, 1]) >>> mt.bitwise_and(mt.array([2,5,255]), mt.array([3,14,16])).execute() array([ 2, 4, 16]) >>> mt.bitwise_and([True, True], [False, True]).execute() array([False, True])
