2. Usage and note
- "x√y" means find the x-th root of y. For example: 3√27=3
- "x^y" means x to the power of y,such as: 2^3=8, 2^(-3)=0.125, (-2)^3=-8, (-2)^(-3)=-0.125
- "n!" means n factorial, n should be positive integer and no more than 170. For example: 5!=5×4×3×2×1=120
- "×" could be ignored between one more brackets and between value and brackets, such as: 3(1+2)(2+3)π(3+1). But can't be ignored between value and constant or function, such as: 3π,, 2sin(90) are both invalid.
- "CPY" can "identify" the value on the cursor intelligently, even to negative number.
- Pressing "CPY" will also copy the value to system clipboard, for other applications. it can not paste the text from system clipboard temporarily.
- Decimal digits can only be choosed in scientific notation mode.
- In main UI, you can press volume up or down key of your device to adjust volume to what you like.
- In constant and function list, the last positon where you have pressed will be remembered for the next use.
- It is recommended that testing your self-defined function before saving it.
- To export saved calculation history texts, it will create texts.xml file at /SuperCalc-backup in SD card.
- To export self-defined constants or functions, it will create constants.xml and functions.xml file at /SuperCalc-backup in SD card.
- You can edit constants.xml, functions.xml or texts.xml file on PC before import, to create your own constants, functions or calculation texts more easily.
- Excuting import will take data from constants.xml, functions.xml or texts.xml to software list. Existed items will be kept, and repeated item will not be import again.
- Excuting export will delete the old constants.xml, functions.xml or texts.xml file on SD card and creat a new one.
- In unit conversion or currency conversion, after you get the converted value, you can press the "ok" button to display result in main UI.
- As default, the software will be install to SD card to save your internal storage if you android version is over 2.2. If you like, you can move it to internal storage.
- Some cyber friends feed back that after installing the new version, the icon will be disappeared. That is because it was intalled in RAM before version 1.38. To solving it is very simple, just uninstall and reinstall will fix.
