### Invert bits in an unsigned integer

```js
import "bitwise"

bitwise.unot(a: uint(v: 1234))// Returns 18446744073709550381 (uint)


```


### Invert bits in unsigned integers in a stream of tables

```js
import "bitwise"
import "sampledata"

sampledata.uint()
    |> map(fn: (r) => ({r with _value: bitwise.unot(a: r._value)}))

```
