Binary operations

Elementwise bit operations

bitwise_and	Compute the bit-wise AND of two arrays element-wise.
bitwise_or	Compute the bit-wise OR of two arrays element-wise.
bitwise_xor	Compute the bit-wise XOR of two arrays element-wise.
invert	Compute bit-wise inversion, or bit-wise NOT, element-wise.
left_shift	Shift the bits of an integer to the left.
right_shift	Shift the bits of an integer to the right.

Bit packing

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