How much precision do you need?
Each row is the same answer cut at a different number of decimals, with what that choice costs you. Pick the shortest row whose error is smaller than whatever you are measuring with.
| Rounded to | Answer (yr) | Off by |
|---|---|---|
| Whole number | 20 | exact |
| 1 decimal | 20.0 | exact |
| 2 decimals | 20.00 | exact |
