About

We’re all quite used to our good old decimal system of numerals. But let’s not forget that there are other ways to count! Whether we need to convert numbers from one system to another just for fun or to store large data more efficiently, a converter proves helpful. In this project, you will create your own tool that will help you convert numbers from one system to another.

Training project

This project allows you to practice and strengthen your coding skills, helping you get ready for more advanced tasks ahead.

What you'll learn

Once you choose a project, we'll provide you with a study plan that includes all the necessary topics from your course to get it built. Here’s what awaits you:

Learn the basics of input and output to implement a simple logic: teach the program to convert the user input number to binary, octal, and hexadecimal systems.

Practice loop, function, and string processing and give your program new functionality: converting user input numbers to the decimal system. Also, add commands to determine what the program should do next.

Upgrade your converter: enable it to convert numbers between any numeral systems. While you're at it, master loops and learn how to store large numbers.

Make it possible for the converter to work with fractions, especially with large fractional numbers.

If you still don't know why 0.1 + 0.2 is not 0.3, this project will definitely help you.
