Price is not $0.6, it is a bit higher.

Limit order

Generation

As we take the user's size and price, round to 2 decimals and multiply them, 6 decimals are enough to produce a set of maker and taker amount at the exact price.

let order = await clobClient.createOrder({
    tokenID: "123",
    price: 0.11,
    size: 21.33,
    side: Side.BUY,
    feeRateBps: 100,
    nonce: 0,
});
console.log("Created Order", order);
console.log("price", Number(order.makerAmount) / Number(order.takerAmount));
console.log();
