<b>How can I remove the ads?</b>\n
|
|
\n
|
|
You can do it by purchasing the special option in the main application preferences.\n
|
|
Purchase is done with Google Play and is linked to your google account.\n
|
|
All your devices where same google account is set will be aware of purchase and will not show the
|
|
advertisement.\n
|
|
\n
|
|
<b>Why Calculator++ needs INTERNET permission?</b>\n
|
|
\n
|
|
Currently application needs such permission only for one purpose - to show ads. If you buy the special option
|
|
C++ will never use your internet connection.\n
|
|
\n
|
|
<b>How can I use functions written in the top right and bottom right corners of the button?</b>\n
|
|
\n
|
|
Push the button and slide lightly up or down. Depending on value showed on the button action will occur.\n
|
|
\n
|
|
<b>How can I toggle between radians and degrees?</b>\n
|
|
\n
|
|
To toggle between different angle units you can either change appropriate option in application settings\n or
|
|
use the toggle switch located on the 6 button\n
|
|
(current value is lighted with yellow color).\n
|
|
Also you can use deg() and rad() functions and ° operator to convert degrees to radians and vice versa.\n
|
|
\n
|
|
<b>Examples:</b>\n
|
|
268° = 4.67748\n
|
|
30.21° = 0.52726\n
|
|
rad(30, 21, 0) = 0.52971\n
|
|
deg(4.67748) = 268\n
|
|
\n
|
|
<b>Does C++ support %?</b>\n
|
|
\n
|
|
Yes, % function can be found in the top right corner of / button.\n
|
|
\n
|
|
<b>Examples:</b>\n
|
|
\n
|
|
100 + 50% = 150\n
|
|
100 * 50% = 50\n
|
|
100 + 100 * 50% * 50% = 125\n
|
|
100 + (100 * 50% * (25 + 25)% + 100%) = 150\n
|
|
\n
|
|
<b>Note:</b>\n
|
|
\n
|
|
100 + (20 + 20)% = 140,
|
|
<b>but</b>
|
|
100+ (20% + 20%) = 124.0\n
|
|
100 + 50% ^ 2 = 2600,
|
|
<b>but</b>
|
|
100 + 50 ^ 2% = 101.08\n
|
|
\n
|
|
<b>Does C++ support fractional calculations?</b>\n
|
|
\n
|
|
Yes, you can type your fractional expression in the editor and use ≡ (in the top right corner of = button). Also
|
|
you can use ≡ to simplify expression.\n
|
|
\n
|
|
<b>Examples:</b>\n
|
|
\n
|
|
2/3 + 5/9 ≡ 11/9\n
|
|
2/9 + 3/123 ≡ 91/369\n
|
|
(6 - t) ^ 3 ≡ 216 - 108t + 18t ^ 2 - t ^ 3\n
|
|
\n
|
|
<b>Does C++ support complex calculations?</b>\n
|
|
\n
|
|
Yes, just enter complex expression (using i or √(-1) as imaginary number).\n
|
|
\n
|
|
<b>Examples:</b>\n
|
|
\n
|
|
(2i + 1) ^ 2 = -3 + 4i\n
|
|
e ^ i = 0.5403 + 0.84147i\n
|
|
\n
|
|
<b>Can C++ plot graph of the function?</b>\n
|
|
\n
|
|
Yes, type expression which contains 1 undefined variable (e.g. cos(t) and t has no value) and click on the
|
|
result. In the context menu choose \'Plot graph\'.\n
|
|
\n
|
|
<b>Does C++ support matrix calculations?</b>\n
|
|
\n
|
|
No, it doesn\'t.\n
|
|
\n
|
|
<b>Why I\'ve got 1.76732452452345E-17 instead of 0?</b>\n
|
|
\n
|
|
Check the \'Round result\' preference in application settings - it should be turned on.\n

<string name="c_hints_content">
|
|
1. You can omit unnecessary multiplication signs (instead of 3*t or t*sin(π*t) just type 3t or tsin(πt))\n\n
|
|
2. Use ≡ (in the top right corner of = button) to simplify expression\n\n
|
|
3. Just click on the result to copy it to the clipboard\n\n
|
|
4. Use = button seldom - result is calculating on the fly\n\n
|
|
5. Add constants for often used values (you can even save expressions)\n\n
|
|
6. Use variables located on 4 and 5 buttons\n\n
