# Bit-wise 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.
`bitwise_invert`(x, /[, out, where, casting, ...]) | 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.
`bitwise_left_shift`(x1, x2, /[, out, where, ...]) | Shift the bits of an integer to the left.
`right_shift`(x1, x2, /[, out, where, ...]) | Shift the bits of an integer to the right.
`bitwise_right_shift`(x1, x2, /[, out, where, ...]) | Shift the bits of an integer to the right.
`bitwise_count`(x, /[, out, where, casting, ...]) | Computes the number of 1-bits in the absolute value of `x`.

## 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.

## Output formatting

`binary_repr`(num[, width]) | Return the binary representation of the input number as a string.
