Description
When I covert the lat, lan values below to polygon and convert the polygon to json using toJson method it removes some digits from lat, lan values(it takes just 6 - 7 digits).
| Lat | Lan |
|---|---|
| 34.8859309407532 | -93.1640625 |
| -15.6230368315283 | -82.265625 |
| -22.917922936146 | -35.15625 |
| -7.01366792756663 | 18.28125 |
| 45.5832897560063 | 2.4609375 |
| 54.3677585240684 | -64.3359375 |
Here is the json output
{
"type": "Polygon",
"coordinates": [
[
[
-93.1640625,
34.8859309
],

Research direction
Start at Polygon.toJson() and trace how the polygon's coordinate values are serialized. Reproduce the issue with the latitude and longitude values in the report, then verify that the resulting JSON preserves the reported precision. The payload does not name a source file or test, so those will need to be located in the repository.
