Project for course IVS/2022

Team: oznuk_1

The calculator app is an app for solving some basic and slightly difficult mathematical problems. The app provides standard mathematical operations and more.

• Ubuntu 64bit
• Windows 64bit

Project was developed in languages: Python. The project was developed by team oznuk_1.

This calculator has root option √ -> in this file marked as ROOT

• Standard mathematical functions
• More functions as: SIN, COS, ROOT, POWER AND FACTORIAL
• Decimal numbers allowed
• The calculator disposes by history of calculations
• The calculator remembers last answer at its 'Ans' button
• The clear button for cleaning the whole input line
• The calculator proceeds factorial numbers, even if the number before factorial is in closed brackets.
• The calculator is able to proceeds integer and float numbers and operations between them infinitely and catches OverflowError and ZeroDivisionError.

These functions can be applied on numbers in this calculator

• Addition: +
• Substitution: -
• Multiplication: *
• Division: /
• Power: x^y
• Sinus: sin
• Cosine: cos
• Root: √
• Factorial: x!

• The calculator rounds results in operations Addition, Substitution, Multiplication, Division, Root and Power to 9 decimal places
• COMMA is used only to divide two expressions in ROOT function

• ADD: <expression> + <expression>
• SUB: <expression> - <expression>
• MUL: <expression> * <expression>
• DIV: <expression> / <expression>
• POW: <expression> ^ <expression>
• SIN: SIN ( <expression> )
• COS: COS ( <expression> )
• ROOT: √NUM or √( <expression> , <expression> )
  • First one is Root with base 2
  • Second one is Root with base NUM2
• FACT: <expression>!

First download the calculator_1.0_amd64.deb package. After downloading the package unpack it by typing sudo dpkg -i calculator_1.0_amd64.deb. Install potential dependencies by running sudo apt-get -f install. Software is now installed under /opt/calculator folder and a helper script calculator is installed under /usr/bin, so you are now able to run the calculator app by just typing calculator from anywhere in the system. Uninstall the app by running sudo apt-get remove calculator.
