  {//from   w  w w  .j  av a2 s. c  o  m
    double x = 9.4;
    double y = 3.5;
    double z = -9.3;

    System.out.println("round(x) = " + Math.round(x));
    System.out.println("round(y) = " + Math.round(y));
    System.out.println("round(z) = " + Math.round(z));
    System.out.println();
    System.out.println("ceil(x) = " + Math.ceil(x));
    System.out.println("ceil(y) = " + Math.ceil(y));
    System.out.println("ceil(z) = " + Math.ceil(z));
    System.out.println();
    System.out.println("floor(x) = " + Math.floor(x));
    System.out.println("floor(y) = " + Math.floor(y));
    System.out.println("floor(z) = " + Math.floor(z));
    System.out.println();
