I'd like to insert NaN values into SQLite database.

I have Ent table with Id, StringColumn and DoubleColumn (not nullable) and I try use the following SQL statement:

INSERT INTO Ent (Id, StringColumn, DoubleColumn) VALUES (1, 'NaN test', ????)

I don't know what to put in place of '????' to have NaN stored.

I'm accessing the database using System.Data.SQLite - maybe this also matters?
