Moved to https://github.com/ryasmi/baseroo - Converts a number represented as a string from one base to another (up to 64).

convertBase.js

function convertBase(value, from_base, to_base) {
  var range = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ+/'.split('');
  var from_range = range.slice(0, from_base);
  var to_range = range.slice(0, to_base);
  
  var dec_value = value.split('').reverse().reduce(function (carry, digit, index) {
    if (from_range.indexOf(digit) === -1) throw new Error('Invalid digit `'+digit+'` for base '+from_base+'.');
    return carry += from_range.indexOf(digit) * (Math.pow(from_base, index));
  }, 0);
  
  var new_value = '';
  while (dec_value > 0) {
    new_value = to_range[dec_value % to_base] + new_value;
    dec_value = (dec_value - (dec_value % to_base)) / to_base;
  }
  return new_value || '0';
}

I moved this code to https://github.com/ryansmith94/baseroo and created issue #1 today and fixed the bug with large numbers. Thanks to @zakariamouhid for the suggested fix, I utilised that and tweaked it to work with TypeScript. Apologies for my slow reply, seemed I had notifications turned off for replies until recently, so thanks to @c0ncentus for persisting with that latest comment which did come through 👍

Now supports floats ryasmi/baseroo#37
