                        if (rb1.isChecked()) {
                            int input = Integer.valueOf(ed.getText().toString());
                            double out = input / 24;
                            out = (double)Math.round(out * 100)/100;
                            Intent m = new Intent(Page.this,MActivity.class);
                            m.putDoubleExtra("res", out);

Since input and 24 are integers, when you divide it, it still produces int. Only then it is converted to double.

One way to solve this: double out = input / 24.0;

DecimalFormat newFormat = new DecimalFormat("#.00"); double twoDecimal = Double.valueOf(newFormat.format(d))

In your code i found is

out = (double)Math.round(out * 100.0)/100.0;
