bit-interleave

Interleaves the bits of up to 32 32-bit integers.

Example

var interleave = require("bit-interleave")

//Create two integers
var a = 0xffffffff
var b = 0x00000000

var c = interleave(a, b)

//Now:
//  c = 0b0101010101010101

Install

npm install bit-interleave

API

var interleave = require("bit-interleave")

interleave(x0,x1,...)

Interleaves the lower order bits of x0 through x1 uniformly.

  • x0, x1, ... A list of up to 32 integers

Returns A single 32 bit integer representing the interleaved bits of x0...x1

To avoid the dynamic look up, you can directly call any of the following methods if you know the number of arguments you are using beforehand:

  • interleave[0]()
  • interleave[1](x0)
  • interleave[2](x0,x1)
  • interleave[3](x0,x1,x2)
  • ...
  • interleave[32](...)
