Chapter 12 Applications of other Bases
Objectives
Convert black and white images to a sequence of numbers.
Convert a sequence of numbers into an image.
Identify colors given as hexadecimal triplets.
Compare shades of grey given as hexadecimal triplets.
Convert a text into a number.
Convert a number into a text.
Numbers written in bases other than the familiar base 10 have many real-world uses. Base 12 used to be popular and is still used for package sizes. Computers store information as base 2 numbers. In this chapter, we give three real-world examples of how numbers in bases other than base 10 are used — encoding images as numbers, describing colors as triples of hexadecimal numbers, and encoding text as numbers.
