1. Better.
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.

2. More accurate
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.

3. complicated.
(((((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 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.
