Dashboard chapter 12 amountInCents = amount * 100 doesn't convert to integer.

In Chapter 12:

The dollar amount is converted to cents by multiplying by 100. However, this doesn't convert it to an integer and can lead to database errors. The value after multiplication needs to be rounded (Math.round(amount * 100)).

For example, entering 2.55:

Database Error: Failed to Update Invoice. NeonDbError: invalid input syntax for type integer: "254.99999999999997"
