1. Better.
This calculator: 5555555555555555^63000000 = 150,8313,8358,2308E991917818.
PC calculator: 5555555555555555^3000. output: invalid input for function.
Ti-80 Plus: 5555555555555555^7. output: ERR: OVERFLOW.

2. More accurate (sometime).
This calculator: sin(179.9999,9999,9999,9999,9999,9999,9999,9) = 1.7453,2925,1994,33E-33.
PC calculator: sin(179.9999,9999,9999,9999,9999,9999,9999,9) = 1.7453,2892,0160,….E-33.
Ti-80 Plus: sin(179.9999,9999,9999,9999,9999,9999,9999,9) = 1.7453,2925E-33.

3. complicated.
(((((ln(87) + e^3) * 56 - sin(69)) * 4!) / 5^(1/2) + pi) * 2.8^1.8) / 3.5 = 2.6890,8945,9852,58E4.

4. Big button, easy to use.

5. Prohibit illegal inputs.

6. Prohibit mean-less inputs.

7. Error check in running time.

8. Output 15 accurate digits.

9. Undo input.

10. easy-read result (result in sections).

Calculating Priority:

1) +, -.
2) *, /.
3) +/-.
4) sin(x), cos(x), tan(x), asin(x), acos(x), atan(x), y^2, y^3, y^(1/2), y(1/3), y^(-1), y^(1/n), y^x, 10^x, e^x, n!.

For same priority, calculating from left side to right side if possible.
For different priority, the higher priority calculate first.
Design for: iPhone 6, iPhone 6 plus, iPhone 5, iPhone 5s, iphone 4s, resizable iPhone.
