1. More accurate than PC calculator:
This calculator: sin(179.9999,9999,9999,9999,9999,9999,9999,9) = 1.7453,2925,1994,3295,7692,3691E-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.

2. More powerful than PC and most student， commercial calculators:
This calculator: 6666666666666666^888888 = 3,9167,0185,4011,6629,1081,8672E14065658.
PC calculator: 6666666666666666^632. output: overflow.
Ti-80 Plus: 6666666666666666 ^7. output: ERR: OVERFLOW.

3. can calculate any complicated expression:
(((((ln(87) + e^3) * 56 - sin(69)) * 4!) / 5^(1/2) + pi) * 2.8^1.8) / 3.5 = 2.6890,8945,9852,58E4.
(((((ln(87) + e^3) * 56 - sin(69)) * 4!) / 5^(1/2) + pi) * 2.8^1.8) / 3.5 = 2.6890,8945,9852,5758,958E4.
(((((ln(87) + e^3) * 56 - sin(69)) * 4!) / 5^(1/2) + pi) * 2.8^1.8) / 3.5 = 2.6890,8945,9852,5758,9584,0598E4.

4. Math and logic calculating, bin-dec-hex data converting.

5. Precisely output 15, 20, 25 digits.

6. Prohibit illegal inputs.

7. Prohibit mean-less inputs.

8. Error check in running time.

9. Big button, easy to use.

10. Undo input.

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

Calculating Priority:

Math:
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!.

Logic:
1) or, and, xor.
2) LShift, RShift, LRShift, RRShift.
3) nor.

For same priority, calculating from left side to right side if possible.
For different priority, the higher priority calculate first.
In logic calculating mode, the data after leftShift, rightShift (righShift), LRShift, RRShift is decimal even in bin or hex mode.
