The autoGeoJSON.precision value cannot be set to more than 6

[Fsystem]

When I set it to 8, the console displays 'memory access out of bounds'.

[jvail]

I ran a quick test with precision 15 and it gave me the correct result. There may be another issue if you have very large objects or many of them. But without a proper bug report I can not do much

[Fsystem]

there is a test data test.zip I do a st_union op with two geojson, select CastToMulti(st_union(GeomFromGeoJSON('${JSON.stringify(geom1)}'),GeomFromGeoJSON('${JSON.stringify(geom2)}')))

[Fsystem]

the 1.geojson is multipart and with holes

[jvail]

Here are test cases for node and browser https://github.com/jvail/spl.js/compare/main...33-the-autogeojsonprecision-value-cannot-be-set-to-more-than-6 and this is the result:

Looks good to me. No clue why it fails for you. Maybe you do not use the up-to-date version of spl.js?

I tried again,and spl is the 0.1.1 latest version,here is my code // init opt autoGeoJSON: { precision: 15, options: 0 } const geom1 =
