    //          note 1: Returns the smallest integer >= x
    //          note 2: JS Math.ceil(-0.5) returns -0, but Python returns 0
    //       example 1: ceil(4.2)
    //       returns 1: 5
    //       example 2: ceil(-0.5)
    //       returns 2: 0
    //       example 3: ceil(3)
    //       returns 3: 3

    // Convert -0 to 0 for Python compatibility
