add ability to show history of previous inputs and outputs

Instead of (sin let's try sin ( because that will reduce the possibility of people getting stuck with the ex4j library error.

We should not be allowed to press del button in case we get a SYNTAX ERROR as our output.

if possible enable decimal formatting:
DecimalFormatSymbols otherSymbols = new DecimalFormatSymbols(Locale.ENGLISH); DecimalFormat decimalFormat = new DecimalFormat( "###,###.########" , otherSymbols ); decimalFormat.format(Double.parseDouble(cNumber));

Use this code and verify before updating master

Even though I place the pointer at say sin ( to make it 35sin, it still gets detected at the latter position. That is becomes this way sin(35);

App crashes when I enter a decimal place and press equal.

Fix is to flag and check for the flag. Maybe a boolean.

3564+++++------ doesn't show syntax error. Or any input of that kind.

Like syntax error delete all of sin cos and tan

Enable copy pasting feature for pre Honey Comb devices too.

Sin pi, cos pi show syntax error.
Put solution around line 474

This will show ∛ on the screen. But cbrt in backend.
Similarly do for all.

Instead of using string output.gettext to check last3chars and delete sin ( cos ( etc try by doing with current cursor position.

Take into account the solution.
May help for cos90 etc.

Avoid Copyright issues.

Don't allow users to edit the syntax error window with more stuff. Lock it if possible.

Delete operation forces cursor to first position/start.

Add pointer style marker to edit stuff already typed

Cant store two same calculations at a time because keys have to be unique.

Remove the existing look and make it more like a Scientific Calculator.
Right now its a basic calculator.

Make TAN90, log0 and exceptions like these display MATH ERROR rather than NaN.
Also E must be written as ^10

Make app function only in Portrait mode. Disable Landscape mode.

For eg, I paste something from Calculator, the color of the pasted text becomes green. Make it standardized black color.

//shouldn't this be String now?
hashMap = (HashMap<String, Double>) mIntent.getSerializableExtra("History_Store");

Just align AC button properly.
