Overview: Calculator++ is an advanced, modern and easy to use scientific calculator #1.
Calculator++ is an advanced, modern and easy to use scientific calculator #1.
Calculator++ is all you need - it helps you to do basic and advanced calculations on your mobile device.
Calculator++ is the modern calculator for everyone: scientists, accountants, students.
++ easy to use
+ no need to press equals button anymore - result is calculated on fly
+ smart cursor positioning
+ several kinds of brackets
+ copy/paste in one button
+ landscape/portrait orientations
++ drag buttons up or down to use special functions, operators etc
++ modern interface with possibility to choose themes (currently 3 themes available)
+ highlighting of expressions
+ history with all previous calculations and undo/redo buttons
++ variables and constants support (build-in and user defined)
++ complex number computations
+ support for lots of functions: sin, sinh, asin, asinh, ln, sqrt etc
++ expression simplification: use 'identical to' sign (≡) to simplify current expression (2/3+5/9≡11/9, √(8)≡2√(2))
+ support for android 1.6 and higher
+ open source
+ Russian and English interfaces
1. You can omit unnecessary multiplication signs (instead of 3*t or t*sin(π*t) just type 3t or tsin(πt))
2. Use ≡ (in the top right corner of = button) to simplify expression
3. Just click on the result to copy it to the clipboard
4. Use = button seldom - result is calculating on the fly
4. Add constants for often used values (you can even save expressions)
How can I use functions written in the top right and bottom right corners of the button?
Push the button and slide lightly up or down. Depending on value showed on the button action will occur.
How can I toggle between radians and degrees?
To toggle between different angle units you can either change appropriate option in application settings or use the toggle switch located on the 6 button (current value is lighted with yellow color).
Also you can use deg() and rad() functions and ° operator to convert degrees to radians and vice versa.
268° = 4.67748
30.21° = 0.52726
rad(30, 21, 0) = 0.52726
deg(4.67748) = 268
Does C++ support %?
Yes, % function can be found in the top right corner of / button.
100 + 50% = 150
100 * 50% = 50
100 + 100 * 50% * 50% = 125
100 + (100 * 50% * (25 + 25)% + 100%) = 150
100 + (20 + 20)% = 140, but 100+ (20% + 20%) = 124.0
100 + 50% ^ 2 = 2600, but 100 + 50 ^ 2% = 101.08
Does C++ support fractional calculations?
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.
2/3 + 5/9 ≡ 11/9
2/9 + 3/123 ≡ 91/369
(6 - t) ^ 3 ≡ 216 - 108t + 18t ^ 2 - t ^ 3
Does C++ support complex calculations?
Yes, just enter complex expression (using i or √(-1) as imaginary number).
(2i + 1) ^ = -3 + 4i
e ^ i = 0.5403 + 0.84147i
Can C++ plot graph of the function?
Yes, type expression which contains 1 undefined variable (e.g. cos(t)) and click on the result. In the context menu choose 'Plot graph'.
Does C++ support matrix calculations?
No, it doesn't
Why I've got 1.76732452452345E-17 instead of 0?
Check the 'Round result' preference in application settings - it should be turned on.
- Integration of ln() and lg();
- Last opened tab is remembered now (history, variables etc);
- Remove option from context menu for variables;
- 1/0 bug;
- Gui defect for MIUI roms;
- Double zero (00) key.
