'decNumber' is not a decimal number.  Both the name and the comment are
wrong.

What about

  function newbase(num, base)
  {
      var digits = [];
      do {
          digits.push(num % base);
          num = Math.floor(num / base);
      } while (num);
      return digits;
  }

?  This is the usual way to to it.
