Examples

Perform a bitwise AND operation

js
import "bitwise"

bitwise.uand(a: uint(v: 1234), b: uint(v: 4567))// Returns 210 (uint)

Perform a bitwise AND operation on a stream of tables

js
import "bitwise"
import "sampledata"

sampledata.uint()
    |> map(fn: (r) => ({r with _value: bitwise.uand(a: r._value, b: uint(v: 3))}))
