bi module on npm, however it has been modified and I wanted to publish the original without modifications. This is jsbn and jsbn2 from Tom Wu's original website above, with the module pattern applied to prevent global leaks and to allow for use with node.js on the server side.
var BigInteger = require('jsbn').BigInteger; var bi = new BigInteger('91823918239182398123'); console.log(bi.bitLength()); // 67
returns the base-10 number as a string
returns a new BigInteger equal to the negation of
returns new BI of absolute value
