Try this:

DecimalFormat df2 = new DecimalFormat( "#0.00" );
double d = 122.00;
System.out.println(df2.format(d));
double dou = new Double(df2.format(d)).doubleValue();
System.out.println(dou);

Output:

122.00
122.0

If you want two digits even its zero after decimal print it as String. double value of 122.00 is 12.0.If you assign double dd = 122.00 and print it will give output 122.0
