> 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.
