title: calculating numbers after . (dot) in java
body: <p>I am new to Java. creating calculator which calculates number from user input.
  I have 2 Jtextfield in my application where user input numbers.
  For example in first field user input 45678.230 and in second field 23214.210 which gives me subtraction result is 22464 but everything i want is full result followed by .(dot) so my answer should be 22464.02</p>
  <pre><code>String n1opn = n1open.getText();
  String n1clsd = n1close.getText();
          
          
  double n1intopen = (int) Double.parseDouble(n1opn);
  double n1intclose = (int) Double.parseDouble(n1clsd);
  double n1ltr = n1intclose - n1intopen;
  
  System.out.println(&quot;output  &quot;+ n1ltr);
  </code></pre>
