Mihai Budiu commented on CALCITE-5986:
--------------------------------------
But changing the family to APPROXIMATE_NUMERIC seems to break quite a few tests.
I will investigate whether it's worth making the change.
According to the SQL standard use of the term, this is a bug, these are
approximate numeric types, e.g.,

> The SqlTypeFamily for FP types is incorrect

> Key: CALCITE-5986
> URL: https://issues.apache.org/jira/browse/CALCITE-5986
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.35.0
> Reporter: Mihai Budiu
> Priority: Minor
>
> In SqlTypeFamily we have this code:
> {code:java}
> private static final Map<Integer, SqlTypeFamily> JDBC_TYPE_TO_FAMILY =
> ...
> .put(Types.FLOAT, NUMERIC)
> .put(Types.REAL, NUMERIC)
> .put(Types.DOUBLE, NUMERIC)
> {code}
> But it looks to me like the type family should be APPROXIMATE_NUMERIC.
> This impacts the way RelToSqlConverter works, for instance.
