Of course there are infinitely many points exactly 788 meters from VK 80000 30000. But almost all of them have some decimal parts in their coordinates. Only eight of them are exactly of the form VKXY where X and Y are 5-digit integers. No round-off is needed.
Enter your solution into the coordinate checker in the form VKxxxxxyyyyy. Hint: there are five 8s in the correct solution. No need to flail the coordinate checker otherwise.
You can validate your puzzle solution with certitude.
