Data representation refers to how information is stored within the computer. There is a specific method for storing integers which is different than storing floating-point values which is different than storing characters. This chapter presents a brief summary of the integer, floating-point, and ASCII representation schemes.
It is assumed the reader is already generally familiar with binary, decimal, and hex numbering systems.
It should be noted that if not specified, a number is in base-10. Additionally, a number preceded by 0x is a hex value. For example, \(19 = 19_{10} = 13_{16} = 0 \times 13\).
