Binary operations

Elementwise bit operations

bitwise_and(x1, x2, /[, out, where, ...])	Compute the bit-wise AND of two arrays element-wise.
bitwise_or(x1, x2, /[, out, where, casting, ...])	Compute the bit-wise OR of two arrays element-wise.
bitwise_xor(x1, x2, /[, out, where, ...])	Compute the bit-wise XOR of two arrays element-wise.
invert(x, /[, out, where, casting, order, ...])	Compute bit-wise inversion, or bit-wise NOT, element-wise.
left_shift(x1, x2, /[, out, where, casting, ...])	Shift the bits of an integer to the left.
right_shift(x1, x2, /[, out, where, ...])	Shift the bits of an integer to the right.

Bit packing

packbits(myarray[, axis])	Packs the elements of a binary-valued array into bits in a uint8 array.
unpackbits(myarray[, axis])	Unpacks elements of a uint8 array into a binary-valued output array.

Output formatting

binary_repr(num[, width])

Return the binary representation of the input number as a string.
