    // Note: there are various round up/down approaches (https://en.wikipedia.org/wiki/Rounding#Tie-breaking).
    //       Math.round uses an approach different from other programming languages, so the results of round function
    //       can be different from other DBMSs. For example, Math.round(-5.5) returns -5. In contrast,
    //       round function in MySQL and PostgreSQL returns -6. The below code is a workaround code for this.
