Method to add two values of type float and integer in Android

Question

Small Android application, which performs addition and other basic operations, and the OnClick() is as follows

@Override
public void onClick(View v) {
    switch (v.getId()) {
           case R.id.btnAdd: 
           isValidToProcess(1);
           break;
           ......
           /*Switch continues for all other operations like Subtraction,etc*/
    }
}

and my isValidToProcess() is as follows

private boolean isValidToProcess(int a) {
    String num1 = mEdit1.getText().toString();
    String num2 = mEdit2.getText().toString();

    if (num1.matches("") || num2.matches("")) 
    {
        ValueEmptyWarning();
    }
    else {
        float numa = Float.parseFloat(num1);
        float numb = Float.parseFloat(num2);
        switch (a) {

        case 1:
            addition(numa, numb);
            break;
              ......
           /*Switch continues for all other operations like Subtraction,etc*/
    }
}

My addition() function

public void addition(float numa, float numb) {
    answer = numa + numb;
    mEdit3.setText(String.valueOf(answer));
    Log.v(TAG, "Error at Subtraction");
}

This program is working fine for Float and Integer numbers, But the problem is, for both Integer and Float values the answer will be in fractions, For example Number1=2 and Number2=3 and the answer=5.0

Objective: If User inputs Integer, The decimal point should not be there.

Is this possible to get the type of Value which user has entered on EditText?

Answer 1

first check for Integer.parseInt(numer) and catch for NumberFormatException . if it will parse it correctly then it is an integer else you can go for float.
