I'm trying to retrieve a public variable from a contract:

pragma solidity ^0.4.4;

contract Test_Uint {
    uint public something;

    function Test_Uint() {
        something = 42;

Note the hard-coded value 42. Here is the test code in truffle:

var thing = artifacts.require("./Test_Uint.sol");

contract('Test_Uint', function(accounts) {

  it("should provide access to something", function() {

    thing.deployed().then(function(instance) {

      instance.something.call().then(function(res) {

I was hoping for 42 or even "42", but it always prints:

{ [String: '42'] s: 1, e: 1, c: [ 42 ] }

What is the right way to access the value?


The result is a BigNumber object. You probably want to do:


See more on this in the BigNumber docs.
