Examples

Shift bits left in an integer

import "experimental/bitwise"

bitwise.slshift(a: 1234, b: 2)// Returns 4936


Shift bits left in integers in a stream of tables

import "experimental/bitwise"
import "sampledata"

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