`ST_DISTANCE_SPHERE` different output in 5.7 and 8.0

I write an open-source library that exposes an API to MySQL GIS functions from Laravel applications.
I run the library's tests on both MySQL 5.7 and 8.0, everything works fine except `ST_DISTANCE_SPHERE` - this function outputs different values for each MySQL version.


```sql
SELECT ST_DISTANCE_SPHERE(POINT(55.5, 23.1), POINT(55.51, 23.1));
# MySQL 5.7: 1022.792591459987
# MySQL 8.0: 1022.7925914593363
```

The difference begins in the tenth digit after the zero.

Any idea why it happens and how can I fix it?
