addQuotes to what? Field names? This can't work in SQLite. addQuotes is for
values, not for identifiers. There are other methods like addIdentifierQuotes
that may be more suitable.

Yes, it does. Chris seems to confuse this with is_numeric. To be sure you can
always add an extra floatval( $var ) or (float)$var to the places where the
variable is used inside of a string, especially if it's a possible SQL
injection.
