Int printing out as scientific notation

Question

maybe doing something stupid here but I can't seem to pick it up.
I have a Window that calls a subclass to display a calculator, and then returns the final value to the Window, if I input 10 digits it prints on as a 12345678E5
something like that.
Anywho here's the two methods that deal with value in the subclass( calculator )
public int ReturnNumber(){//the method that will return the value from the keyboard
   int final_number = Integer.parseInt(number); 
    return final_number;   // returns value to question screen
  private void NextButtonActionPerformed (java.awt.event.ActionEvent evt) {
   if ( value.length() != allowable_answers[currentQuestionNumber] ){
                 JOptionPane.showMessageDialog(this, "Please make a valid entry.", "Invalid",
                 JOptionPane.WARNING_MESSAGE );
                 value.replace(0,counter,""); 
                 jTextField1.setText( null );
                 return;
    else {
            number = value.toString();
           setVisible(false);
           frame.final_number = ReturnNumber();
           frame.userMakeSelection = true;
           frame.FinalTimer.start();
           frame.ButtonSelected();Code from window that deals with the number
if(Numeric[currentQuestionNumber]){
            currentAnswers[currentQuestionNumber][1] = final_number;// currentAnswers is a float[][]
            numeric_question_value[currentQuestionNumber][0] = final_number;// used in poll frequency
          }// numeric is a int[]
        else
            currentAnswers[currentQuestionNumber][currentChoice] = currentChoice;Is from trying to jam an int into float?
Any suggestions

Answer 1

Is from trying to jam an int into float?That's exactly the cause. Here are some solutions:
- Use java.text.DecimalFormat to format the output or cast the float to an integer type when you want to print it (presicion might become a problem).
- Keep the number in an int or long all the time. This way you'll not lose any presicion.
Explanation can be found in the API docs of Float.toString():"If the argument is NaN, the result is the string "NaN".
Otherwise, the result is a string that represents the sign and magnitude (absolute value) of the argument. If the sign is negative, the first character of the result is '-' ('-'); if the sign is positive, no sign character appears in the result. As for the magnitude m:
If m is less than 10^-3 or not less than 10^7, then it is represented in so-called "computerized scientific notation." Let n be the unique integer such that 10n<=m<1; then let a be the mathematically exact quotient of m and 10n so that 1<a<10. The magnitude is then represented as the integer part of a, as a single decimal digit, followed by '.' (.), followed by decimal digits representing the fractional part of a, followed by the letter 'E' (E), followed by a representation of n as a decimal integer, as produced by the method Integer.toString(int) of one argument."
