Calculator Plus helps you to do basic and advanced calculations on your mobile device.
IMPORTANT:
1. Always check angle units and numeral bases: trigonometric functions, integration and complex number computation work only for RAD!!!
2. Application contains ads! If you want to remove them purchase
special option from application settings. Internet access permission is needed only for showing the ads. ADS ARE ONLY SHOWN ON THE SECONDARY SCREENS! If internet is off - there are no ads!
Features:
* easy to use
* home screen widget
* no need to press equals button any more - the result is calculated automatically
* smart cursor positioning
* 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
* 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 a huge variety of functions
* expression simplification: use 'identical to' sign (≡) to simplify current expression (2/3+5/9≡11/9, √(8)≡2√(2))
Why Calculator plus needs INTERNET permission?
Currently application needs such permission only for one purpose - to show ads.
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.
Examples:
268° = 4.67748
30.21° = 0.52726
rad(30, 21, 0) = 0.52726
deg(4.67748) = 268
Does Calculator Plus support %?
Yes, % function can be found in the top right corner of / button.
Examples:
100 + 50% = 150
100 * 50% = 50
100 + 100 * 50% * 50% = 125
100 + (100 * 50% * (25 + 25)% + 100%) = 150
Note:
100 + (20 + 20)% = 140, but 100+ (20% + 20%) = 124.0
100 + 50% ^ 2 = 2600, but 100 + 50 ^ 2% = 101.08
Does Calculator Plus 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.
Examples:
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). ONLY IN RAD MODE!
Examples:
(2i + 1) ^ = -3 + 4i
e ^ i = 0.5403 + 0.84147i
