### 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)}))
```
