Turn a treasure note of walking directions into one exact tile, without drifting

A clue says walk so many paces one way, then so many another way, from an old landmark. If every leg is rounded to whole tiles on its own, the dig spot ends up a tile or two off. Here is where to round, and what to do about it.

Why this works

Every rounding throws away a little, and the losses pile up with each leg. Keeping the exact walk and rounding once at the end means the error can never grow beyond half a tile, however long the clue is, so the dig spot stays honest.

When not to use it

Not for a game where the player walks the route step by step on a grid and each step must land on a real tile. There, move tile by tile and let walls interrupt the walk, as exact decimals would hide a blocked path.
