YUJIN Transform Algorithm:


function yujinTransform(lat, lng) {

  const latPart = Math.floor(((lat + 90) / 180) * 999999);

  const lngPart = Math.floor(((lng + 180) / 360) * 999);

  return `${latPart.toString().padStart(6,'0').slice(0,3)}-${latPart.toString().padStart(6,'0').slice(3)}-${lngPart.toString().padStart(3,'0')}`;
