Fundamental mathematical calculations are required to be performed in every step of human life. In most of the places such as in shops, hotels, medicals, schools etc., separate calculators are used for calculation.

The comparison between existing traditional calculators and the proposed Calculator app for Android can be done in the following points:

  1. Size: The separate calculators are larger in size due to use of own circuit board whereas android calculator is installed in cell phones.
  2. Power: A small battery power of cell phone is enough for running android calculator but traditional calculator consume comparatively higher power.
  3. Accuracy: The accuracy of both the calculators depends upon their programming. Calculators can be designed for the desired accuracy.
  4. Cost: Android Calculator, being an application, can be downloaded free of cost and installed on phone. The traditional calculators have their own hardware. As a result of this, they need to be purchased.
  5. Ease and comfort: Most of the android cell phones are of touch screen type. So, calculator app Android is easy and comfortable to use.

Features:

  • It is easy and comfortable to use.
  • The application can be easily downloaded and installed on any android cell phone and tablet.
  • It provides the facility to perform fundamental mathematical operations.
  • The application gives fast and accurate result.
  • This application consumes very small power of your cell phone.

When the Calculator App is executed, Main.Xml layout code will run. This is the first design layout that will load features such as height, width, background details, etc.  Then, the java file, calculator activity, will load design parameters like buttons, click functions, text display, etc. AndroidMainfest.xml is the main configuration file of the project that will load the main layout by default.
