Generates uniformly distributed ints in any base from a bit sequence, according to the algorithm described by Christian Perfect.
$ npm install sequin
Construct a stream using an array of
1 values, or using a
the second argument set to
var Sequin = require('sequin'), crypto = require('crypto'), stream = new Sequin(crypto.randomBytes(10), 8);
generate(k) method returns an integer less than
there are not enough bits left in the stream to generate an integer of the
var Sequin = require('sequin'), stream = new Sequin([1,1,0,1,0,1,0,1,1,1,1,1,0,0,1]); stream.generate(5) // -> 3 stream.generate(5) // -> 3 stream.generate(5) // -> 1 stream.generate(5) // -> null
