public static void main(String[] paramentros) {

    // Ask for user input
    System.out.print("Enter 1st value:");

    // use scanner to read the console input

    double valorAtualizado = Double.parseDouble(valor) * 8.333;
    double calculoMultiplo = 10 * (Math.ceil(Math.abs(valorAtualizado / 10)));

    System.out.println(calculoMultiplo);

    double teste = (double) Math.round(Double.parseDouble(valor) * 8.3d) * 10 / 10d;
    System.out.println("TEste:" + teste);

    System.out.println("Result of the operation is " + valor);

    System.out.println(Precision.round(0.912385, 0, BigDecimal.ROUND_HALF_UP));
