We all know and love our number system, called base 10, also known as decimal. Each digit in a number has 10 possible values, ranging from 0 to 9. When a digit exceeds 9, it rolls over, back to 0, and we add 1 to the digit to the left. Starting at the rightmost digit (or the digit to the left of the decimal place), the ones column, each digit to the left is 10 times greater than the one to the right, hence their names "ones column", "tens column", "hundreds column", etc. However, base 10 isn't the only number system around. Notably, the transistors inside a standard computer use base 2, also known as binary. These devices are also called "digital" because the pieces that make them work can be either on or off. In base 2, each digit in a number has 2 possible values, 0 or 1. When a digit exceeds 1, it rolls over, back to 0, and we add 1 to the digit to the left. Starting at the rightmost digit (or the digit to the left of the decimal place), the ones column, each digit to the left is double the value of the one to the right. And same goes for other bases. This project converts decimal numbers to each base 2 through 16 and shows their values. Visualizing these numbers is a great way to understand different bases.
