generate n random numbers from the same seed

HDR Unofficial port to JS (Hubbard Decision Random Number Generator)

// I haven't die hardered any of this. HDR passed. I wrote the js code based on what I found in Excel formula. CAUTION
// seed = 6345484 // change when you want a new starting point for a stream of random numbers
// PM_Index = 0 // where on stream do you want to grab random number from? Increment to n for n seeded random numbers

  const largePrime = 2147483647;

  const tenMillion = 10000000;
  // Do we need this in js? is there a modulo?
  function MOD(n, m) {
    var remain = n % m;
    return Math.floor(remain >= 0 ? remain : remain + m);
  }
