Okay, so leaving out the affinity just lets it default to BLOB. That clarifies
and simplifies things.

Is there a way to pass binary representations of floating point numbers to
a SQL query? If sqlite's internal representation of floating point
numbers is 8-byte IEEE doubles, it would be convenient to be able to pass
the literal value of a float or double to the underlying SQL parser
