We’re used to counting in the decimal numeral system, which uses 10 digits: 0
through 9. This system likely developed because humans counted on their
fingers, and most people have 10 fingers. But other number systems exist.
Computers make use of binary, a numeral system with only two digits, 0 and 1.
Programmers also sometimes use hexadecimal, which is a base-16 numeral system
that uses the digits 0 to 9 but also extends into the letters A to F.

We can represent any number in any numeral system, and this program displays a
range of numbers in decimal, binary, and hexadecimal.
