sqlite

What steps will reproduce the bug?

I am assuming parameters that are number are always bound as type double, but integers should be bound as type integer so that SQLite performs integer arithmetic and returns a type of integer instead of a type of double.

const db = new DatabaseSync(':memory:', { readBigInts: true });
const big = db.prepare('select 2 * 2');
const bigResult = big.all();
const notBig = db.prepare('select 2 * ?');
const notResult = notBig.all(2);

This is the offending code in nodejs:
https://github.com/nodejs/node/blob/19c46abbefdb8711b913d7237b3c1299367f87d7/src/node_sqlite.cc#L2703

How often does it reproduce? Is there a required condition?

Every time

What is the expected behavior? Why is that the expected behavior?

Integers should be bound as integers not double as they are integers.

What do you see instead?

Integers being bound as double.

Research direction

Start in src/node_sqlite.cc at the linked parameter-binding code and reproduce the issue with the provided DatabaseSync examples. Verify how numeric parameters are classified before SQLite receives them. Done means integer parameters produce SQLite integer arithmetic and the reported readBigInts behavior is covered by regression testing.
