  • / By Iren

The calculator in the smartphone is one of the irreplaceable classic functions, which will always be relevant in any gadget. It will help the housewife calculate the amount of the cost of the products in the supermarket, and the scientist – on the move to estimate the complex formula. If you get bored with a standard calculator preinstalled in a smartphone, you can download a special application that will be interesting not only for the variety of features but also for stylish design. We have chosen several programs for Android for mathematical calculations, which will, of course, facilitate your life in various situations.

Calculator by Xlythe

Often we need to make calculations that can not be done with the Android stock calculator, and we start looking for an application that has additional capabilities.

And this is already taken care of by the Xlythe developer, who released an extended version of ICS calculator equipped with a serious set of additional functions.

Here are its main features:

  1. Addition, subtraction, multiplication, division.
  2. Extended functions, such as logarithms, SIN, COS, irrational numbers like pi and e.
  3. Calculation of complex numbers.
  4. Construction of function graphs.
  5. Working with matrices: addition, multiplication, determinants, and eigenvalues.
  6. Supports work with hexadecimal and binary numbers.
  7. Display history.
  8. Support for tablets and smartphones.

This application has not only a wide range of additional peculiar properties, it still has the fully open source code. Thanks to all this, the calculator from Xlythe will be the default calculator in such a super popular alternative Android firmware as CyanogenMod.

It is worth noting that this calculator is based on the stock calculator Android 4.0/4.1, so it will not work in earlier versions of the operating system. However, if you are using Android 4.0 or higher, you can use this calculator in parallel with the stock application.

Calculator (CyanogenMod)

The developers of this calculator for Android have tried to combine the possibilities of plotting and matrix calculations with the simplicity and convenience of the interface. This was achieved by dividing the functions into several panels, switching between them by a simple gesture of paging. At its core, the Calculator (CyanogenMod) is the modifier of the standard Android calculator and replaces it after installation. For the user, two options for graphic design are available – dark and light. In addition to standard algebraic operations, direct and inverse trigonometric functions, complex numbers, matrices, and graphs of functions are affordable.

Support for three radix systems allows you to switch them at any time, which automatically converts all the numbers in the dialog box. The application is equipped with widgets for quick access even when the screen is locked. An animated history of results supports the function of copying values by long pressing on the required result. Quick and convenient movement between panels allows to not waste time on search of a necessary key. By splitting functions into thematic panels, all keys are of sufficient size even on the smallest screens. The calculator is compatible with any smartphones and tablets and supports automatic screen orientation change.
