quadratic-equations

About quadratic-equations

quadratic-equations is a tiny project that simply finds the roots of polynomial equations with degree 2 with real/complex coefficients.

Date of creation of CLI: January 15, 2020
Date of creation of GUI: September 27, 2020

The driver files for this project are available both as a command-line interface and a graphical-user interface.
While the CLI is a one-time run program, the GUI can be used multiple times in the single run. The GUI also creates logs of the equations solved and traces errors (through logging) as well.

Edit the logging settings

To modify the level of the logger, modify:

logging.basicConfig(
    filename="quad-equations-logs.log", level=logging.DEBUG, format=LOG_FORMAT
)

on Line 59 of gui.py to:

logging.basicConfig(
   filename="quad-equations-logs.log", level=LEVEL, format=LOG_FORMAT
)

where LEVEL can be one of:

• logging.INFO
• logging.DEBUG
• logging.WARNING
• logging.ERROR
• logging.CRITICAL

Footnotes

• The project only supports equations of the type ax² + bx + c = 0, i.e. purely quadratic equations.
• The coefficient a of x² cannot be set equal to 0.

Run

Clone the repository on your device and navigate to the folder.

To run the command-line interface, execute:

python3 cli.py

To run the graphical-user interface, execute:

python3 gui.py
