Metric prefix​

Number.prototype.prefix = function (precision, base) {

  var units = ' K M G T P E Z Y'.split(' ');

  if (typeof precision === 'undefined') {
    precision = 2;
  }

  if (typeof base === 'undefined') {
    base = 1000;
  }

  if (this == 0 || !isFinite(this)) {
    return this.toFixed(precision) + units[0];
  }

  var power = Math.floor(Math.log(Math.abs(this)) / Math.log(base));
  // Make sure not larger than max prefix
  power = Math.min(power, units.length - 1);

  return (this / Math.pow(base, power)).toFixed(precision) + units[power];
};

function benchmark(run) {
  var start = performance.now();
  run();
