> Key: CALCITE-638
> URL: https://issues.apache.org/jira/browse/CALCITE-638

>
> Per the SQL standard,
> * the SQL REAL type is a 4 byte floating point number (thus maps to Java
> float),
> * FLOAT is up to 8 bytes (thus maps to Java double), and
> * DOUBLE is 8 bytes (thus maps to Java double).
> A number of places in Calcite map FLOAT to float values, and I think a few
> others map REAL to double.
