Question

Please help me to solve this. I trying to get value from textview and stored as string. Then it converts to double. While converting up to 7 characters functioning normally but if i try to add more than 7 result is 1.23456789E8. Here is my code

String value = tvInput.getText().toString();
\\tvInput is my textView
Double result = 0.0;
Double input1=0.0;
Double input2=0.0;
input=Double.parseDouble(value);
result = input1 + input2;
tvInput.setText(Double.toString(result));

if i give input1 value as 1234567 and input2 as 1234567 i am getting correct result but if give input1 as 12345678 and input2 as 3. the output is 1.2345681E7

The value you get is correct, the issue is with the way you print it.

You’re relying on toString for a double output; if you want to guarantee not to have an exponential notation, you should format it using a DecimalFormat, or with String.format;

DecimalFormat myFormatter = new DecimalFormat("############");
tvInput.setText(myFormatter.format(result));

Also see the format documentation
