NAME
====

Bits - provide bit related functions

SYNOPSIS
========

    use Bits;  # exports "bit", "bits", "bitcnt"

    say bit(8, 3);    # 1000 -> True
    say bit(7, 3);    # 0111 -> False

    say bits(8);      # 1000 -> (3,).Seq
    say bits(7);      # 0111 -> (0,1,2).Seq

    say bitcnt(8);    # 1000 -> 1
    say bitcnt(7);    # 0111 -> 3

DESCRIPTION
===========

This module exports a number of function to handle bits in unsigned integer values.

SUBROUTINES
===========

bit
---

    sub bit(UInt:D value, UInt:D bit --> Bool:D)

Takes an unsigned integer value and a bit number and returns whether that bit is set.

bits
----

    sub bits(UInt:D value --> Seq:D)

Takes an unsigned integer value and returns a `Seq`uence of the bit numbers that are set in the value.

bitcnt
------

    sub bitcnt(UInt:D value --> Int:D)

Takes an unsigned integer value and returns the number of bits that are set in the value.
