        Double amout =  Double.parseDouble(amount.getText().toString());

        Double samount = amout * 180;


        Toast.makeText(MainActivity.this, "S. " + rsamount.toString(), Toast.LENGTH_SHORT).show();

        Log.i("price", amount.getText().toString());

here is the function in kotlin to convert number in two decimal point.

fun roundOffDecimal(number: Double): Double? {
        val df = DecimalFormat("#.##")
        df.roundingMode = RoundingMode.CEILING
        return df.format(number).toDouble()
    }

Try this

EditText amount = findViewById(R.id.amount);

int amout =  Integer.parseInt(amount.getText().toString());

int samount = amout * 180;

String converted = new DecimalFormat("0.00").format(samount);
