kgyrtkirk opened a new issue, #18205:
URL: https://github.com/apache/druid/issues/18205
For a value like `0.1` the best float / double representation is different.
right now:
* `RangeFilter` doesn't match in these cases
* `EqualityFilter` does match
`Filtration` rewrites single-value `RangeFilter` to `EqualityFilter` which
makes this issue in most cases absent.
`RangeFilter` works like:
```
assertFilterMatches(
new RangeFilter("d0", ColumnType.FLOAT, 60.0f, 60.0f, false,
false, null),
ImmutableList.of("4")
);
assertFilterMatches(
new RangeFilter("d0", ColumnType.DOUBLE, 60.0f, 60.0f, false,
false, null),
ImmutableList.of("4")
);
assertFilterMatches(
new RangeFilter("f0", ColumnType.FLOAT, 10.1f, 10.1f, false,
false, null),
ImmutableList.of("1")
);
assertFilterMatches(
new RangeFilter("f0", ColumnType.DOUBLE, 10.1, 10.1, false, false,
null),
ImmutableList.of()
);
```
meanwhile for `EqualityFilter` matches:
```
assertFilterMatches(new EqualityFilter("f0", ColumnType.FLOAT, 10.1,
null), ImmutableList.of("1"));
assertFilterMatches(new EqualityFilter("f0", ColumnType.DOUBLE, 10.1,
null), ImmutableList.of("1"));
```
