|
Features:
|
|
- Scientific number format core code. Support range 10^-999 ~ 10^999
|
|
- Number of significant figures up to 10
|
|
|
|
Limitations:
|
|
- Right now, only accept "num, operator (+,-,*,/), num, =" input sequence.
|
|
Input "3, +, 5, -, 2, =", the calculator will only do 5-2 and result = 3
|
|
You have to input "3, +, 5, =, -, 2, =" to get 3+5-2 = 6
|
|
|
|
- "*,/" have no priority. Actually you can't input 3+5*2 yet.
|
|
|
|
User Instructions:
|
|
use arrow button to move cursor, "play" button to select, "off" button to exit
|
|
F1: if typing numbers, it's equal to "Del"; otherwise, equal to "C"
|
|
F2: circle input "+, -, *, /"
|
|
F3: equal to "="
|
|
|
|
"MR" : load temp memory
|
|
"M+" : add currently display to temp memory
|
|
"C" : reset calculator
