Comment:
Per http://article.gmane.org/gmane.comp.db.sqlite.general/75696 , SUM
values should not have affinity so typecasting Decimal into a string will
never return real values.
I think changing the typecast of Decimal into float is "good enough".
Internally, sqlite3 already represents these values as floats, and it
would fix this bug. Otherwise, we would need separate casting engines
depending on whether SUM is used.
