Calculator

I need a Visual [url removed, login to view] Calculator done up. Nothing fancy. I can show a GUI to whoever wins the bid, its very simple though and can be done in a few minutes. Basically its the windows calculator. Another project follows if this one is done well.

## Deliverables

When using the calculator you should be able enter the digits by clicking on the numeric buttons. You should not be able to enter digits into the display text box.

"+/-" Button - Changes the sign of the number in the display. The negative should be visible and the positive should not. Hitting it repeatedly should not make multiple signs appear.

"." - enters a decimal point in the display. Any number may only have one decimal.

Must implement 4 signs; addition, subtraction, multiplication, and division. Do not allow user to divide by zero or provide an appropriate error handling.

"=" - completes the previously entered math operation. if you press it repeatedly it repeats the last operation.

"backspace" - erases the rightmost digit in the display.

"clear" - clears all of the internal memory of the calculator.

"CE" button - clears the last entered number from the display. It does not clear the result of the last operation, operand ect.

--For testing purposes it needs to be able to do the following:

1 + 2+3+4+5 = to 15

1+2-3+4-5 = to -1

1+2*3/4-5 = to [url removed, login to view]

1+2+3+4 = = = to 18

1+2+3+++4 = 10

3+4 = -5 = to 2

2+3 = 9 -5 = to 4
