java - Rounding Off For a Cell -


using following code trying round off double value nearest whole number eg 2.3 2.0 ,2.6 3.0.but if pass value 2.5 per math.round function should return 3 getting output of 2 

private static void adddata(table b) throws exception {     font font = new font(color.black);     cell cell = null;     double value = 143.567;      cell = new cell(new phrase(roundoffvalue(value), font));     cell.sethorizontalalignment(element.align_center);     table.addcell(cell);     }  public static string roundoffvalue(double value ) {    return string.valueof( new float( math.round(value))); }

math#round() round 2.5 3. docs state:

returns closest {@code long} argument, ties rounding positive infinity.

// prints 3. system.out.println(string.valueof(math.round(2.5d)));  // prints 144. system.out.println(string.valueof(math.round(143.567)));
