56 - Scientific number format core code. Support range 10^-999 ~ 10^999
57 - Number of significant figures up to 10
60 - Right now, only accept "num, operator (+,-,*,/), num, =" input sequence.
61 Input "3, +, 5, -, 2, =", the calculator will only do 5-2 and result = 3
62 You have to input "3, +, 5, =, -, 2, =" to get 3+5-2 = 6
64 - "*,/" have no priority. Actually you can't input 3+5*2 yet.
67 use arrow button to move cursor, "play" button to select, "off" button to exit
68 F1: if typing numbers, it's equal to "Del"; otherwise, equal to "C"
69 F2: circle input "+, -, *, /"
72 "MR" : load temp memory
73 "M+" : add currently display to temp memory
74 "C" : reset calculator
